Any Lower & it Would Just be a Crash

Jalopnik: "Cesar Falistocco, Captain of Argentina Aerobatic Squadron as he raises Argentina and Chile's flags with the wingtip of his plane skimming the grass". The previous low, also from the apparently astonishingly macho Argentines was about 1 meter (jet trainer). This looks like the left wing tip was ---oh, I don't know---3 inches? 5 cm?
