Another variation is also used in the same context:
Belly up - could also be referring to the underbelly of an aircraft or boat.
: : Do not think this means "to fall over on ones back". Rather, "to go wrong". Believe origin is early floating navigation instruments in aeroplanes designed to turn over when not working so as not to mislead pilot. Undersides resembled a pair of t i t s.
