Harvey Nelson Sweetman, DFC (10 October 1921 – 15 January 2015) was a New Zealand fighter pilot of the Second World War.

Harvey Sweetman was born on 10 October 1921 in Auckland, New Zealand, and educated at Matamata District High School in the Waikato, where he was swimming champion and captain of the 1st XI cricket team.

Three weeks later, while escorting Bristol Blenheim bombers attacking a power station at Rouen, he engaged a Bf 109 that was encountered on the return flight to England.

485 Squadron flew a mission escorting bombers attempting to disrupt the Channel Dash by the German battleships Scharnhorst and Gneisenau.

During this mission, Sweetman, together with another pilot, shot down a Bf 109 that was attempting to engage their flight leader, Bill Crawford-Compton, west of Ostend.

This was recorded as shared with another pilot; although Sweetman was adamant that no other aircraft was involved, the surviving crew of the bomber were certain a Spitfire had shot them down.

[4] Despite Sweetman's success, the squadron's night-fighting operations were mostly uneventful and after a number of weeks it was switched to day-fighters, converting to the Hawker Typhoon.

[4] At the end of the month he had to crash land his Typhoon near Selsey village on returning from a mission escorting fighter bombers to Le Havre.

[16] In July Sweetman, having flown operationally for nearly two years, left the squadron for an instructor's post at RAF Charmy Down before taking up production testing for the Hawker Aircraft Company.

486 Squadron became heavily involved in Operation Diver, the campaign to protect London and southeast England from the V1 flying bomb offensive.
