At some stage in the 70’s the Boscombe/Farnborough Hunter was used to acquire data to validate FLIR (Forward Looking Infra Red). Although when I was involved in such ‘games’ it was at night, in winter, and in the Brecon Beacons, in company with some Gentlemen from Hereford! Sidcup by day would have been much more preferable!!!!!!!!!!!!!!
