Video of what appears to be Boeing test flights of the 777 and 747 in heavy crosswind situations. The video appears to be used to promote pilot training with Aeroclube in Brazil.
The titling is in Portuguese, but rougly translates to:
Not every day we find calm winds
What should you do in those situations?
Return to the times of the aviation clubs
Remember your instructor’s (teachings)
And make a safe landing
These pilots were certainly flying conventional aircrafts.
Learn with the best!
Clearly, these are excellent pilots, but I have to believe the pucker factor can still be measured on the Richter scale.
