[1][2] Najib was born in Kaimganj to Israil Ahmad Khan of the Afridi tribe of Pashtuns, from the Khyber Pakhtunkhwa province of Pakistan, on 24 August 1933.

In 1962, he was again sent to the United States for more Advanced Training Courses and after returning, he was posted as the Officer commanding (OC) of the 31st Tactical Attack wing's elite No.

During his tenure with the Squadron, Najeeb also assisted Chuck Yeager on a flight to Mount Godwin Austin and took some memorable pictures of him in a PAF F-86F over the mountain.

[6] The B-57 bombers would arrive over their targets in a stream at intervals of about 15 minutes, which led to achieving a major disruption of the overall IAF effort.

[7][8] During the 1971 war, Najib served as the PSO[clarification needed] of the PAF's Commander-in-chief, Air Marshal Abdul Rahim Khan.

[2] One of 8-Pass Charlie's confirmed kills is an Indian Air Force MiG 21s on Operational Readiness Platform (ORP) which was about to take off when he executed the first raid on the Adampur airbase at 2200 hours with his lone B-57 on 6 September, 1965.

To disguise the direction of his run, he used to cut throttles before entering a dive and by the time the ack-ack opened up he was beneath the umbrella of fire.

He flew 17 bombing missions against various Indian Air Force operational bases and led his Squadron with courage during the most hazardous raids on Ambala, Adampur, Jamnagar and Jodhpur.

He carried out the raid on the well-defended airfield of Ambala deep in enemy territory at great personal risk.
