Lyneham to Glasgow to Swansea to Lyneham?
Sounds like a useful MCT trip - just add a few minutes for the onload/offload of the medical team.... Probably all achieved within the available training budget, but more importantly it achieved a lot more than endless NDB holds over Wooty B.
Not in the same league, but even on the old FunBus we occasionally managed to do things on training trips which wouldn't have been possible otherwise - such as an airways training trip for a brace of co-piglets to Paderborn and back to drop off a medical team, for example. Much better value than droning round a triangular route and back to Brize to do the pilot change - because for once we did something useful!
