Planes fly if their speed relative to the air is high enough to produce lift. If there is no wind, the plane's air speed will be the same as its ground speed. If flying against wind, its ground speed will decrease.
That said, what was the lowest ground speed during landing ever recorded?
I think there should be some rules against landing with the wind from behind, as it would make the plane go too fast, but what about opposite? Has any plane landed with zero, or close to zero ground speed? How about 'negative' speed, pushing the plane backwards relative to the ground?
I found some information about the highest ground speed while in flight, but I'm interested in the exact opposite.
Highest points for answers with passenger airplanes (737 etc), helicopters are considered cheating.
