the aircraft wing rode over the roof of the van and did not for example strike the van head on and spin around or anything like that. Under these circumstances most of the loading will have been in the vertical plane not the horizontal.
That makes it OK??????????
had red paint from the wing scraped along the roof edge; so the impact was enough for that at least
How can anyone guess at the unseen damage? At the very least it needs properly inspecting. What a stunning display of airmanship (NOT) I hope red van man reads this thread - he can't be impressed either
