I can wonder, "How does that aircraft look and fly?", and then get a
segfault with gdb backtrace...
Conditions to reproduce: turn on Aircraft shadow, bump clouds, and 3d
clouds, before starting this aircraft.
This model has 46697 vertices and 48172 faces. But loads okay with the
above mentioned turned off. Reminds me of the segfaults I used to get
when my model was too big.
It tried to dereference a null pointer.
