The Indian Army had been helping the Mukti Bahini, through
Operation Jackpot, since May 1971, while the Indian Navy had helped set up the Bengali Naval commando unit and had provided command staff for the Bengali gunboats, which were busy mining riverine craft and harassing merchant marine operations in East Pakistan. The IAF could not come to grips with the PAF until formal hostilities commenced, but the Bengali airmen joined in as 9 Bengali pilots and 50 technicians - formerly of the PAF and serving with the Mukti Bahini in various capacities - were gathered for a special mission on 28 September 1971 at
Dimapur in
Nagaland.
[25] A number of Bengali civilian pilots from the PIA later joined this group. Indian civilian authorities and the IAF donated 1
DC-3 Dakota (given by the Maharaja of
Jodhpor), 1
DHC-3 Otter plane, and 1
Alouette III helicopter for the newborn Bangladesh Air Force, which was to take advantage of the lack of night-fighting capability of the PAF to launch hit-and-run attacks on sensitive targets inside Bangladesh from the air. The Bengali rank and file fixed up the World War II vintage runway at Dimapur, then began rigging the aircraft for combat duty. The Dakota was modified to carry 500 pound bombs, but for technical reasons it was only used to ferry Bangladesh government personnel. Captain Abdul Khalek, Captain Alamgir Satter, and Captain Abdul Mukit, all destined to earn the
Bir Pratik award, piloted the Dakota. The helicopter was rigged to fire 14 rockets from pylons attached to its side and had .303 Browning machine guns installed, in addition to having 1-inch (25 mm) steel plate welded to its floor for extra protection. Squadron Leader Sultan Mahmood, Flight Lieutenant Bodiul Alam, and Captain Shahabuddin, all of whom later won the
Bir Uttam award, operated the helicopter. The Otter boasted 7 rockets under each of its wings and could deliver ten 25 pound bombs, which were rolled out of the aircraft by hand through a makeshift door. Flight Lt. Shamsul Alam, along with Captains Akram Ahmed and Sharfuddin Ahmad, flew the Otter - all three were later awarded
Bir Uttam for their service in 1971. This tiny force was dubbed
Kilo Flight, the first fighting formation of the nascent Bangladesh Air force.
Under the command of
Group Captain A.K. Khandkar and
Squadron Leader Sultan Mahmood, intense training took place in night flying and instrumental navigation. After 2 months of training, the formation was activated for combat. The first sortie was scheduled to take place on 28 November, but was moved back 6 days, to 2 December 1971. The Otter - flown by Flight Lt. Shamsul Alam, with co-pilot F.L. Akram - was moved to Kailashsahar, and was prepared for a mission against targets in
Chittagong. The helicopter, piloted by Flight Lt. Sultan Mahmood and Flight Lt. Bodiul Alam, was to hit Narayangang, flying from Teliamura.
In the early hours of 3 December 1971, the twin Otter and the helicopter took off from their respective bases and hit the oil depots at Naryanganj and Chittagong,
[26] which the Mukti Bahini guerrillas had been unable to sabotage due to tight security.
[27] Ironically, the PAF initiated
Operation Chengis Khan on the same night, and the IAF commenced offensive operations in the East from 3 December 1971. Kilo Flight would, in total, fly 12 missions in 1971, hitting various targets in Chittagong, Naryanganj, and Bhairab.
[25] The formation base was moved from Dimapur to Shamshernagar after it was liberated on 4 December, then was finally moved to Agartala before the end of the war. The BAF contingent was present in Dhaka when the surrender ceremony took place on 16 December 1971.
