Offley was Headquarters for an
Auxiliary Territorial Service (ATS) Searchlight unit based in Hoo Lane, that had detachments in Hitchin along Bedford Road, Chapel Foot along London Road, as well as at
Whitwell and
Diamond End.
Lancaster bomber crash At 7.15am on 18 July 1944 a
Lancaster Mk.111 bomber belonging to
115 Squadron RAF crashed into the farmhouse at West End Farm () killing the crew as well as the farmers wife and two daughters (one of whom was home on leave from the
Auxiliary Territorial Service). The aircraft LM616 (KO J) had left its base at
RAF Witchford near
Ely several hours earlier to support
Allied ground forces taking part in
Operation Goodwood during the
Normandy campaign. The
Royal Air Force and
United States Army Air Forces objective was to bomb units of the
16th Luftwaffe Field Division and the
21st Panzer Division which were located around
Caen,
France. LM616 received severe damage during the raid, in which its controls and navigation aids were shot up. The aircraft had descended through low cloud only to see the high escarpment of the
Chiltern Hills at Offley loom into view too late for the crew to take immediate action. The aircraft hit trees in a wood on top of Birkitt Hill before colliding with the farmhouse at West End Farm.
Glebe Farm Explosion At 3 pm on 8 January 1945, a US Army lorry carrying
munitions was involved in a road accident with a petrol tanker as it was passing Glebe Farm at the Flints. The drivers managed to evacuate nearby residents; however, a bus from Luton came round the corner just as an explosion occurred, killing three US servicemen on the bus and injuring 21 others. The explosion was so severe that it made a crater on the road 50 feet wide and 14 feet deep. The Windmill and Farm were completely destroyed and Flint cottages were severely damaged, other houses in Offley suffered extensive blast damage. ==Population==
