For the pleasure of colorful and spectacular crashes of my kills, i use "FireDOWN" FX package by LouieG, which contains a heavily modified version of fx_fatal_explosion_l. So you can imagine my surprise the first time i saw this model's nose explode away mid-air in a most colorful display, complete with a ground shock wave too, which is exactly why I don't use his companion MidAir Fire FX "SkyAFIRE" pack. It leaves way too much color spash and weirdness in the sky in an extreme takedown scenario. I don't mind it so much on the ground in a crash, but not in the sky. I think the use of this ground related fx_fatal_explosion_l call in mid air explosions may have confused the sim as well, resulting in kills still flying about long after they should have crashed.
