Wing Commander Karun Krishna 'Jumbo' Majumdar, DFC & bar (6 September 1913 – 17 February 1945) was an officer in the Indian Air Force.

On the very next day, the Imperial Japanese Army Air Force based in Mae Hong Son in Thailand bombed Taungoo, inflicting considerable damage.

Majumdar immediately planned retaliatory action, even though the Westland Lysander was an army co-operation aircraft not meant to serve either as a fighter or as a bomber.

Slinging two 250-pound bombs on the stub wings of a Lysander, he set off solo on 2 February 1942 towards the Japanese airbase at Mae Hong Son.

Majumdar took considerable risk in flying low and dropping bombs accurately on target, destroying the enemy hangar, aircraft and airfield.

On the next day, Majumdar led the entire squadron in a bombing mission and destroyed the aircraft, wireless installations and the buildings.

On one occasion Majumdar was forced down in the Shan jungles due to engine failure and managed to return to Lashio after a harrowing journey through dense forests.

[2] After converting to North American Mustang aircraft at 41 OTU (Operational Training Unit), Majumdar joined No.

In his first operational flight on 10 June 1944, he made a reconnaissance of the Seine River and carried out ground-strafing of enemy targets.

[2] Because of his superb piloting skills and indomitable spirit, Life magazine featured him in its issue of 15 May 1944 among twelve of the world's most outstanding airmen.

[2] On the afternoon of 17 February 1945, Majumdar took part in a flying display at Walton, near Lahore in a Hawker Hurricane.

[3] The following epitaph appears on the marble headstone of his grave at Lahore: "Go, passers-by / And do if you can as he did / A Man's part / In defence of liberty.
