I think this is an ad for a South American flight school.
Regardless, have you ever wondered if those huge Boeing jets can land nearly sideways? The answer, apparently, is yes.
These are test videos for the 777 and 747, designed to see how well the jets perform in a strong crosswind. Since they are in the Boeing livery, they don't belong to an airline.
Seeing how well these things perform in a scary landing gives me even more confidence in the equipment.
