He was just saying you shouldn't necessarily assume (if you were) that every person intentionally crashes because its easy to lose control and crash unintentionally when you get shot up.

It's actually really easy to stay up after you've been shot to bits if your plane isn't spinning out. Most people can't be bothered and push the nose down slightly.

Best advice is to stick with people you know you can have good games with.

I play arcade, since i dont have much fun in playing sim, so when people crash most of the time its on purpose, since well arcade lets u fly on with insane damage sometimes :P
I never intentionally crash my plane its lame, did have several runins with tree's and buildings when trying to get away from people.

Had a game earlier where some guy would just instantly dive head first into the ground if i would even hit him once, he didnt even need heavy damage or smoke pouring out of him.
It seems that was his fix for not being able to get out of my sights.
