No matter what you do, the AI airplanes are invulnerable on the ground, and while flying they have a shield barrier like a starship form Star Wars active around them too.
In short: you CAN crash, if you check the option in the sim. The AI
WON'T EVER crash for no reason on this simulator.
It's a hard coded behaviour that has me mad too, the times I collide with AI. I remain there burned and smoking or fall from the sky in pieces, and they go away, and you could swear they laugh at you. >:( >:(

There's but one real cure for human stupidity. It's called DEATH.
At the moment mourning the assassination of sarcasm and irony for the good of the "higher".
