There's nothing overly scary about these landings, they are perfectly normal crosswind landings with no danger to the aircraft or passengers. The videos have been inceased in speed so it looks more dramatic than it is, they are not in real time. While the winds were on the strong side that particular day, it's nothing out of the ordinary and many users of these forums have probably been on flights like that. I know I have on several occasions, some with greater crosswinds than those. If you've ever observed aircraft landing, you'll appreciate it's a normal day in flying aircraft and not something you normally see as a passenger.
