Folks:
The ladies were ATA (Air Transport Auxiliary) ferry pilots: the lady in the Spitfire's cockpit in the main photo looks exactly like a noted British aviatrix called Lettice Curtis, herself an ATA pilot and probably included in the group photo though I can't pick her out. They flew every type there was - Hawker Tempests, Avro Lancasters, Short Sunderlands even, and in all weathers. An intrepid bunch!
Regards
John
