AI planes that have to back-taxi and turn around in a pull-out run into each other.

[deathbysybian]

I had several AI flights leaving Qeshm airport on the PG map.  One would back-taxi down the runway while the others wait.  When the plan pulled into the U-turn area the waiting AI detected the runway was clear so started back-taxiing itself.  The Ai in the U-turn area pulls back into the runway and initiates take-off.  The two collide.  Then they eventually de-spawn and the process begins again.  Eventually they all annihilate each other.
