What happened
During a local flight training mission, a four-engine aircraft was engaged in the process of towing a glider. Shortly after the aircraft departed from the runway and entered its initial climb phase, a critical mechanical failure occurred involving the towing equipment. The rope used to connect the glider to the towing aircraft became wrapped around the elevator control surface.
This entanglement disrupted the flight controls, leading to an immediate loss of control. The aircraft subsequently crashed during the early stages of the ascent. There were no survivors among the eight crew members on board the aircraft.
