In Capt. Johnny Sadiq's book 'Come Fly With Me - Jets', there's an incident described in which a PIA Trident was struck by a vulture in September 1969. The aircraft was operating Lahore to Rawalpindi flight under the command of Capt. Baakza with Safdar Nana as Co-pilot.
Shortly after take-off from Lahore, a vulture struck nose section of the Trident, penetrated aluminium skin of the aircraft, through pressure bulkhead, came out of instrument panel, glanced off the control column and struck the flight commander Baakza a severe blow on his inner thigh. The captain was now covered in blood and only semi-conscious on the aircraft which was rapidly depressurising with deafening wind blowing into the cockpit. Co-pilot Nana called Lahore for emergency landing, slowed down speed of the aircraft.
Nana asked Flight Engineer to remove semi-conscious captain from his seat to prevent disruption of flight controls during emergency landing. Nana also asked Flight Engineer to sit on captain's seat so that he had someone to select his slats, flaps, and landing gear while he concentrated on bringing the damaged Trident back on ground.
The Trident was safely landed by Nana at Lahore Airport.
