How is this for a BAD day ?


Aircraft Commander 1st Lt. Oliver Hildebrandt, Pilot 1st Lt. Walter Ross,
and Co-pilot Captain Wilbur Evans, and a crew of thirteen took off from
Carswell AFB in B-36B, 44-92035 of the 26th Bomb Squadron of the 7th Bomb
Wing at 5:05 A.M. on November 22,1950. The planned 30-hour training mission
consisted of air-to-air gunnery, bombing, simulated radar bombing, and
navigational training.

Immediately after take-off, the #4 alternator would not stay in parallel
with the other three alternators, so it was taken off-line and de-excited
three minutes into the flight. About one minute after the #4 alternator was
shut down, flames 8 to 12 feet long erupted from around the air plug of the
number-one engine. The left scanner reported the flames to the pilot. Six
minutes after take-off, the flight engineer shut down the number-one engine,
feathered its propeller, and expended one of its Methyl bromide fire
extinguishing bottles.

The mission continued on the power of the remaining five engines. 44-92035
cruised to the gunnery range on Matagorda Island at an altitude of 5,000
feet. It arrived at 7:00 A.M. and the gunners began practicing. Radar
Observer S/Sgt. Ray Earl manned the tail turret. The charger for the right
gun burned out, so he expended just half of his ammunition. Then the APG-3
radar for the tail turret started acting up, so S/Sgt. Earl secured the set.

Aircraft Commander 1st Lt. Oliver Hildebrandt noted that the vibration from
firing the 20mm cannons increased significantly during the fourth gunnery
pass. Immediately afterward, radar operator Captain James Yeingst notified
Hildebrandt that the APQ-24 radar set blew up and was smoking. Vibration
from the firing of the guns was causing shorting between the internal
components of the radar. Then the liaison transmitter failed as well.

The cannons in the left forward upper turret and the left rear upper turret
stopped firing. The gunners attempted to retract the gun turrets, but the
failed turrets would not retract. Gunner S/Sgt. Fred Boyd entered the turret
bay, but other problems began to take precedence over the stuck turrets.
Boyd was called out of the bay before he could manually crank the turret
down.

At 7:31 A.M. the number-three engine suffered an internal failure. The
torque pressure fell to zero. The manifold pressure dropped to atmospheric
pressure. The fuel flow dropped off, and the flight engineer could not
stabilize the engine speed. The pilot shut down the number-three engine and
feathered its propeller. The B-36B had only one operating engine on the left
wing, so the pilot aborted the remainder of the training mission and set
course for Kelly Air Force Base.

Flight engineer Captain Samuel Baker retarded the spark, set the mixture
controls to "normal", and set the engine RPMs to 2,500 to increase the power
from the remaining engines. Unknown to Captain Baker, the vibration from the
guns had disabled the electrical systems controlling the spark settings and
fuel mixture. He immediately discovered that the turbo control knobs no
longer affected the manifold pressure.

The B-36B could not maintain its airspeed on the power of the four remaining
engines. It descended about 1,000 feet and its airspeed bled off to 135
miles per hour. The pilot called for more power. The flight engineer
attempted to increase engine speed to 2,650 RPM and enrich the fuel mixture,
but got no response from the engines except for severe backfiring. The fuel
mixture indicators for all of the engines indicated lean.
The second flight engineer, M/Sgt. Edward Farcas, checked the electrical
fuse panel. Although the fuses appeared to be intact, he replaced the master
turbo fuse and all of the individual turbo fuses. He noticed that the
turbo-amplifiers and mixture amplifiers were all cooler than normal. He
climbed into the bomb bay to check the aircraft power panels and fuses, but
could not find any problem there.

Kelly Air Force Base had a cloud overcast at just 300 feet and the
visibility was restricted to two miles. The weather at Bergstrom Air Force
Base not as bad, with scattered clouds at 1,000 feet, broken clouds at 2,000
feet and 10 miles visibility. Carswell Air Force Base was clear with 10
miles visibility, but it was 155 miles farther away than Bergstrom. Air
traffic control cleared all airspace below 4,000 feet ahead of the crippled
B-36B. Aircraft Commander Hildebrandt was flying on instruments in thick
clouds.

The poor weather at Kelly Air Force Base convinced Hildebrandt to change
course from Kelly to Carswell Air Force Base, passing by Bergstrom Air Force
Base on the way in case the airplane could not make it to Carswell.
Bombardier Captain Robert Nelson made two attempts to salvo the 1,500 pounds
of practice bombs in the rear bomb bay, but the bomb bay doors would not
open by automatic or manual control, or emergency procedure.

There was no way to dump fuel to reduce the weight of the B-36B. The flight
engineers resorted to holding down the switches used to prime the fuel
system in an attempt to increase fuel flow to the engines. M/Sgt. Edward
Farcas held down the prime switches for the number-two and number-four
engines while Captain Baker held down the prime switch for the number-five
engine and operated the flight engineer's panel. The configuration of the
switches did not allow them to prime the number-five engine and the
number-six engine at the same time.

The high power demand coupled with the lean fuel mixture made the cylinder
head temperatures of the engines climb to 295 degrees C. Flight engineer
Baker jockeyed the throttles, decreasing the throttle setting of the engine
with the highest cylinder head temperature until another engine grew even
hotter. The high temperature caused the gasoline/air mixture in the
cylinders to detonate before the pistons reached top dead center,
diminishing power and damaging the engines.

Despite the critical situation with the engines, Aircraft Commander
Hildebrandt decided to continue past Bergstrom Air Force Base to Carswell.
Bergstrom was overcast and its runway was only 6,000 feet long. Carswell
offered a much longer runway. By the time the B-36B reached Cleburne , the
backfiring on all engines increased in violence. The number-2, number-5, and
number-6 engines were running at 70% power and the number-4 engine was
producing only 20% power. The airspeed had dropped off to 130 miles per
hour.

Aircraft Commander Hildebrandt attempted to restart the number-one engine,
the one that had spouted flames on take-off, but fuel was not getting to its
induction system. He tried to restart the number-three engine, but could
not unfeather the propeller on that engine. As the bomber passed to the west
of Cleburne , the right scanner reported dense white smoke, oil, and metal
particles coming from the number-five engine.

After a short while the number-five engine lost power, and Aircraft
Commander Hildebrandt feathered the propeller on that engine while still
twenty-one miles from Carswell Air Force Base. The B-36B could not stay
airborne on the power of the three remaining failing engines. It was flying
at just 125 miles per hour, seven miles per hour above the stall speed,
losing both altitude and airspeed. Howard McCullough and W. Boeten were
flying Civil Aeronautics Authority DC-3 N342 near Cleburne . They were
notified by Meacham Tower to be on the lookout for 44-92035. They spotted it
about five miles south of Cleburne . They observed that the number-one and
number-three propellers were feathered and the number-five engine was on
fire. They turned to follow the descending bomber. Aircraft Commander
Hildebrandt ordered the crew to bail out of the stricken bomber.

Bombardier Captain Robert Nelson had bailed out of airplanes on two previous
occasions. He had crash landed twice and ditched once. He was the first man
to bail out from the forward crew compartment. He suffered contusions of his
lower spine when he landed.

Radar Operator Captain James Yeingst responded to stress with laughter and
jokes. He was a bit giddy before the bailout. He was the second man to exit
from the forward crew compartment. His parachute streamed after he pulled
the rip cord. He passed Captain Nelson going down. Captain Yeingst's
parachute mushroomed open just before he hit the ground, but he suffered
fatal injuries.

Co-pilot Captain Wilbur Evans was the third man to exit from the forward
crew compartment. He had bailed out of airplanes twice before and crash
landed several times during WW-II. This time he broke both bones in his
lower right leg when he landed.

Navigator Captain Horace Stewart had previously tried to get off flying
status because he felt that the B-36 was too dangerous. It is reported that
during the hour before bailout, he was tense, nervous, and chain-smoking. He
was the fourth man to bail out from the forward crew compartment. He pulled
his rip cord right as he exited the forward escape hatch on the left side of
the fuselage. His parachute opened and pulled him toward the number three
propeller. His head hit the downward pointing blade of the propeller,
killing him instantly.

Radio Operator Cpl. Paul Myers followed Captain Stewart out the escape
hatch. Myers landed with minor injuries. Flight Engineer M/Sgt. Edward
Farcas jumped head first through the exit hatch of the forward crew
compartment right after Cpl. Myers. His parachute did not open when he
pulled the rip cord. He pulled the parachute out of its pack with his hands
and landed with only minor injuries.

Radar Mechanic Robert Gianerakis and Flight Engineer Captain Samuel Baker
were the next to escape from the forward compartment. Both landed with only
minor injuries. Radio Operator Sgt. Armando Villareal bailed out after
Captain Baker. Villareal did not trust his parachute to open, so he pulled
the rip cord while he was still in the forward crew compartment. He held his
parachute in his arms as he jumped feet first through the escape hatch.
Despite his unorthodox method of escape, he landed with only minor injuries.

Pilot 1st Lt. Walter Ross was the next to last to leave the forward
compartment. He landed with only minor injuries. Gunner S/Sgt. Andrew Byrne
and Radar Observer S/Sgt. Ray Earl were the first two crew members to bail
out of the rear crew compartment. Both landed with only minor injuries.
Gunner Cpl. Calvin Martin was the third man to exit the rear crew
compartment. He was swinging under his parachute as he hit the ground. He
broke his right ankle as he landed. He fell backward onto a rock, fracturing
his third lumbar vertebra and compressing his tailbone.
Gunner S/Sgt. Ronald Williams followed Cpl. Martin out the rear escape
hatch. He landed with only minor injuries. Gunner S/Sgt. Fred Boyd was the
last man to exit the rear crew compartment. He called to Aircraft Commander
Hildebrandt over the intercom to let him know that everyone had escaped from
the aft compartment. When he turned back to the exit hatch, it had fallen
shut. He had to open the hatch again to make his escape. He broke the fibula
of his left leg when he landed farther to the north than the other crew
members.

After S/Sgt. Boyd reported that all other crew members had bailed out of the
rear compartment, Aircraft Commander Hildebrandt set the autopilot and
jumped clear when the bomber was less than 1,000 feet above the ground. He
and nine other crew members escaped from the B-36B with only minor injuries.
When McCullough and Boeten in DC-3, N342 saw the parachutes of the escaping
crew members, they announced the bail-out on the emergency frequency of
121.25 megacycles.

Each report of Emergency Parachute Jump indicates that the incident occurred
20 miles south southeast of Carswell Air Force Base. The descent of the
B-36B was witnessed by Mr. Buck Bell and his wife, who lived about 5 to 7
miles southwest of Crowley , Texas . Mr. Bell saw the crew members
parachuting from the bomber, but did not see it hit the ground about one
mile north of his house. Mr. James Bandy and his wife were on the road to
Cleburne about 4 miles from their house on Route 1 near Joshua when they
spotted the B-36B trailing smoke, flying in a nose-high attitude. They saw
it hit the ground in a level attitude, raising a cloud of dust.

The B-36B descended straight ahead in a nose-high attitude for a mile after
Aircraft Commander Hildebrandt bailed out. It stalled, pitched nose down,
and impacted in a terraced field on Less Armstrong's Dairy, 14 miles south
of Carswell Air Force Base, 2 miles west of the South leg FTW range, and six
miles west of Crowley at 9:50 in the morning. The forward crew compartment
separated and folded underneath the rest of the fuselage. The tail section
broke off, and the rear crew compartment came away from the mid-fuselage as
the wreckage slid 850 feet along the ground and twisted to the right.

The rear sections of the airplane remained largely intact. The elevation at
the crash site was approximately 700 feet. Mr. W. Doggett witnessed the
bail-out and crash from his home on Route 1 near Joshua. The B-36B impacted
about 2-1/2 miles north of his house. He drove to the crash site in his
pickup truck and helped the surviving crew members to regroup.

Four minutes after the crash, McCullough and Boeten in DC-3, N342 reported
that two Navy aircraft were circling the wreckage. The wreckage smoldered
for about eight minutes before a fire broke out in the number-six engine.
The 15,000 gallons of remaining fuel consumed the forward fuselage and
wings. The civilians and crew members were driven away from the crash site
by exploding ammunition and the knowledge of the presence of 1,500 pounds of
bombs aboard the airplane.

Another thought on this.......

I wonder why the crew didn't attempt to start the four J-47 jet engines, which were mounted outboard of the recip engines, 2 each in a pod? Hence the old phrase, six turning and four burning.

The jet engines didn't appear until later models. The B-36B was powered by 6 ea Pratt and Whitney's.

Might have been the early model perhaps? Without the J-47's.Just looked and the J-47's were on the B-36D model. :d

Mindsets were wholly different back then. Today, likely the crew would abort and land with merely the alternator problem. But, perhaps not. However, without question they would abort and land when the first engine had to be shut down.

The experience of that crew helped to reshape mindsets over the next few decades.

Aviation was vastly more risky back then. Those guys took risks as a matter of normal course that today we would not take.

I knew a retired air force nco, who was a gunnery instructor on B-36's. They were going on tdy to make a fly over at 50,000ft..they turned wrench's for a week and never got it off the ramp. He went on to tell me, "every time we fired the thing up, something would quit working, fail, or break" they ended up leaving it there and flying back in a DC-3, told he heard it sat there for months. Old "iron pants" was not too pleased.

haha, I know that pain all to well.


As for those pour souls, I commend their bravery. It's too bad we lost a few of them, and I'll have a drink for them the next time I get a chance.

Ill drink to that (na) beer! I seem to always run into old "pistons and props" guys from all over the place, and get to hear a lot of good old storys. Like the time my old pappy was stationed in japan in 46' him and some buddys hitched a ride on a C-46 heading to some big city for a evening of "cocktails and company" and this old pilot of the C-46 wanted to get back right away for his party. So the crewchief got the bright idea of pulling out some of the RF spark plug suppresors off one of the engines, so the engine would miss and not turn the proper RPM during at runup, thus the crew chief says we cant takeoff, so I will fix it tomarrow and stay the night. Now this old C-46 driver was not gonna miss his party back at the base so he says "Were taking off anyway the plugs are just fouled, they will clean out and run" The look on our faces..we all turned white with fear, scared the H*** out us. Before the crewcheif could confess, the pilot finnaly relented and told him fix it now, and they did and lived to tell about it. Needless to say they never tried that agian, and that old pilot never did find out what happend. God knows a 46' need all them horses working to fly.

I agree with Ken about the mind set. The PIC may have reasoned that the mission profile might be altered to include just how much can get accomplished with the loss of one engine. If I remember my history the accumulation and application of military data and experience was incessant during those years. These guys were on the edge of knowledge and fear of new enemies was the drum beat.
