Previous paragraph to the one above:
On 19 September 1958 No. 77(SM) Squadron received its first Thor missile, which was flown to Feltwell aboard a USAF C-124 Globemaster, and all subsequent missiles were delivered by this means, along with their ancillary equipment. The missile was still being operationally proven as a weapons system however, and nearly a year was to elapse before the next batch of RAF squadrons was declared operational with the Thor, on 22 July 1959. These were No. 82(SM) at Shepherd's Grove, Suffolk, No. 104(SM) at Ludford Magna, Lincolnshire, No. 106(SM) at Bardney, also in Lincolnshire, No. 107(SM) at Tuddenham, Suffolk, No. 113(SM) at Mepal, Cambridgeshire, No. 142(SM) at Coleby Grange, Lincolnshire, No. 220(SM) at North Pickenham, Norfolk, and No. 269(SM) at Caistor, Lincolnshire.
