The one whose transponder location was zig-zaggy is the one that was at low level during the fly over -- that zig-zag is the map trying to map the location of the jet with transponder OFF. But the video at the stadium showed it was part of the group of 3 bombers in formation.
One more screen shot showing they were one over the other -- flying together -- see timestamps in Mountain Standard Time (2 hours before Tampa time).
