Had just re-armed a single AR 234 once and was lining up just past the end of the runway to take off again and got flipped over by the trucks, and had to take a ditch. Yeah, that was many months ago. I'd really like to see the truck thing fixed. Had a truck convoy pass over the runway the other night when I was taking off in a 262. It was like half the runway away from me when it passed, but that still shouldn't be happening.
