Harrier had 'Lepus' Flare capability, as did
Phantom FGR2 - 6 Sqn in UK - and Buccaneer.
41 Sqn also did trials with a much modified
Port outer fuel tank - very, very bright 'flash gun'.
Saw flashes in the sky over Wainfleet on many occasions... from Coningsby.
The Role Bay chief at the time - '72-75 - Pa**y Sc***on's garden fence in Sleaford was constructed from (empty) Lepus Flare boxes.
