For those who have not yet seen it: in the Warbirds library there is a very nice Heinkel P 1179A nightfighter. This WWII plane did not make it beyond the drawing board but was to have been operational in 1946. There are both FS2004 and FSX versions. If you have Acceleration you will need the canopy glass fix, also in the SOH library. The gunsight is not transparent in Acceleration, but you can replace it with the gunsight of one of your other planes (at least that worked for me).
