Perhaps the crew mistook the right runway edge for the left runway edge, and the “bounce” was from crossing the intersecting runway. If the runway was completely snowed over at the time of approach, could’ve been possible.
Once upon a time I saw an FO in training at 1:22 AM line up a Beech 1900 over the runway edge lights (he thought they were centerline lights) to land out of an NDB. Just before flare height my Instructor (group lesson, swapping seats) calmed said “go around”. Edge-lander got sent home and I got a reality check.
