Haven't picked up the fact that the aircraft is called the Hawker Siddeley Gnat, because that's who actually built them for the RAF. The aircraft had been designed by Folland, but by the time the MoD ordered them Folland's Aircraft division had been absorbed into Hawker Siddeley Aviation. Its the same for a lot of aircrat built in the early to mid 1960's. Early Harrier, Most people incorrectly called it the Hawker Harrier, the only jump jet built by Hawker was the P1127, all the rest before BAe was formed, (Kestral and GR1/3 T2/4 Harriar) were built by Hawker Siddeley (HSA). Lightning, early ones built by English Electric, most of them built by British Aircraft Corporation (who absorbed EE's aviation assests in 1960), same for VC-10 (Vickers didn't build aircraft when that aircraft actually made production), Trident (DH was histroy, part of HSA when the type entered service).
