I saw the Frecce Tricolori at Toronto Island Airport about a month before their horrible accident. Upon takeoff the outside aircraft rolled upside down with the landing gear down, retracted their gear as the inside aircraft did the same thing in the opposite direction, then they sucked their gear in. They climbed out upide down then righted them selves, the outside aircraft rolling left, the inside aircraft rolling right. They did this while remaining about 5 feet from each other. Totally Awesome!!!!
