#79, BEagle: Rotodyne. Funded not as a LCY downtown girl -economics would make no sense, but as upfront military inserter. We tussled with the legacy of Heavy Gliders and of paras excreting from Daks. Expensive, in every way. We had an on/off thought in 1953 of (free) C-119 Packets, then in 1957 contemplated DHC-4 Caribou...or Rotodyne. We chose to take SAL TwinPins. Rotodyne dribbled on a MoS Research budget where RAE's bright ideas sat, as yet unwanted by Requirors (V/STOL, jet flap, BLC by suction...those things). Hovercraft sat there too. By 1960, as Westland took over all UK rotors, big turboshaft helis were becoming credible (to be Chinook was in hand!) UK chose to put its money into turbine S.58 (to be Wessii), some, not much, into Belvedere as inducement to WAL to take Bristol Helicopter Divn. Rotodyne as orphan.
#52 SOSL: Spey into Phantom as dole. No. RN wanted out of P.1154 and told Ministers that Spey, and only Spey, could handle the bolter case on Ark Small. (It doesn't actually matter whether anyone here cares to contest that. Ministers accepted professional advice, remembering the very public loss of O/C of first Scimitar Squadron embarkation).
When P.1154(RAF) was chopped, RAF wanted 175 F-4D, bog (J79)-standard, offered at fixed price, fixed delivery, on credit. Roy Jenkins, MoA, turned that into 66 Harrier GR.1 and 116 F-4M/Spey: he knew TSR.2 was about to expire, and saw this package as means of preserving, not dole for some, but any industry at all.
