Amazing video from a test airport in Brazil. The planes practice landing in really strong cross winds, (crab landings) some look like they are coming
in almost sideways.
This little item shows the Boeing factory determining the demonstrated crosswind landing limits on the 777 and the 747SP. The engineers make educated
guesses, but then the test crews have to go actually prove the numbers. They sneak off to Brazil to do these tests at a certain remote BAF airbase
famous for its continual atrocious crosswinds...Should the gear sideloads be excessive and fold one up, there is nobody there to take nasty pix for
the Airbus guys to wave around in the press."
