The markings and codes on this aircraft have been changed regularly over the years. This livery, that of a night-fighter was carried for a short time. The ground crew is seen getting a lift out to the flightline prior to the display. Considering the wooden construction of the aircraft, it seems surprising that this was allowed !
This was an in flight refuelling demonstration at a Mildenhall Air display. The F1-11 are 73-0712, 73-0713 & 61-0885 all from nearby Lakenheath. The 'tanker' is an EC-135H 61-0285 which was retired due to excessive corrosion at Mildenhall in 1988.
