To reinforce what you and Rocky have said...
A KC-135 with 20 SOB was shooting an approach to Wurtsmith AFB from the north. The pilot in the left seat was a major who had just returned to flying duty was flying the aircraft, called for gear down. The copilot lowered the gear, the warning light stayed on and the gear indicators showed that the nose gear wasn't down and locked. You have to go down into the lower nose compartment (which is a pain in the a$$) to check the gear through an observation window. The gear looked okay and it appeared that the NLG doors were closed. The aircrew got tied up trying to resolve the issue, somebody accidentally disconnected the auto pilot altitude hold. Clear weather, bright daylight, the airplane flew straight and level into the ground near Alpena Michigan. Fifteen fatalities, the crewchief who was in the back of the aircraft survived. He tried to re-enter the burning aircraft to assist people escape but some that perrished couldn't release their seatbelt.
