Were any of these 'touch and go' landings?
I have had 3 aborted landings in my life. The first was on Eastern in MIA in '86 -- the wheels did a hard bounce on the runway, followed by a softer bounce and then immediately full power and back up.
My other two times (a BA 747 @ DEL in '92 and DL Shuttle @ LGA in '08) seem to be more common with everyone else... got down to about 100 feet and then went around without touching the ground on the first attempt.
