How insanely low can you fly an airliner? This crazy

This is madness: watch this crazy pilot celebrate 100 years of Argentinian civil aviation with the longest and lowest flyby I've ever seen. That plane is a 94-foot wingspan Boeing 737-500 capable of carrying 132 passengers. This is even crazier than my previous favorite low pass:

And then you have this B-52 Stratofortress madness flying lower than the deck of the USS Ranger aircraft carrier, a few feet above the waters of the Persian Gulf in 1990.
