Airplanes Crashing?

[Keaner]

I have seemed to get a lot of planes crashing. Is there a secret to preventing them from crashing?

[planetmaker]

There are two secrets:

a) there are small and big airplanes. Big airplanes have a high chance of crashing on small airports (small and commuter).
b) you can disable airplane crashes somewhere in the advanced settings (->vehicles->number of plane crashes).

Have also a look at the manual / wiki.
