The weapon lacked any speed sensors to detect free fall from an aircraft, i.e., intentional dropping in flight, so if the weapon accidentally fell off an aircraft parked on a flight deck and rolled overboard it could detonate when it sank to the preset depth.
The weapon lacked any speed sensors to detect free-fall from an aircraft i.e., intentional dropping in flight. As a result, if an armed Mk 101 bomb accidentally fell off an aircraft parked on a flight deck and rolled overboard, it could automatically detonate when it sank to the preset depth.
