This C-5M (callsign RCH965 – 87-0036) had just offloaded its cargo at RAF Fairford before departing to a local airfield. I was expecting a flat, slow climb out, and set myself up at the 09 end of Fairford’s runway. As you can see, this particular aircraft was clearly light, and by the time it got to the runway threshold was at least 1,500ft.
