Which prompts me to ask: you often see Hercules and smilar tactical transport aircraft demonstrate the "Que San" (sp?) approach at airshows - and I've also seen RAF/RN Jetstreams do it in the past; do they use reverse thrust to keep the speed back during the descent; or is there sufficient drag from the flaps to keep things in hand, or indeed do they just accept an increase in airspeed?
Always wondered...
