The Boeing 737 was authorized to descend to flight level 190 and was notified of the other aircraft's Mode C issue. Both aircraft landed at their destinations with no injuries to occupants and no damage to the aircraft. ## Aircraft Specifications The Boeing 737-33VSF is a transport-category aircraft with a retractable tricycle landing gear.
