26-5-2014 USAF Boeing Globemaster 3 Tail Number 10-00221 (P221) working callsign "Reach 104" today. This aircraft is based at Charleston AFB. Photographed Overhead North West England,UK at Altitude 38,000ft (12km). She looks so graceful in the cruise !
Searching the usual Internet databases, not many photos of this aircraft are available. I was Lucky having a clear sky to capture this very fine looking C-17 .
