That long nose was hard to see over. On 29 July 1999, a flight of a Bearcat and two F4Us were taxiing for takeoff at Oshkosh. The Bearcat stopped and the first F4U ran into it, destroying both aircraft. Then the second F4U veered off the taxiway and was substantially damaged. I’m pretty sure the lead F4U was actually owned by Vought and being flown by a company exec.
I was in Oshkosh two years ago when two Mustangs collided upon landing. They were flying formation and the second one hit the one in front of him.
From what I understand the second always lands first and then then the plane leading comes next.
