Back in 1976 I was a civvie with the cadets and did a nav course at Finningley.
During the week there was a series of astro fix flights and they allowed us to go along. I ended up on XS729 (G) and recall at the end we did a practice emergency descent back into Finningley. Great way to end a three hour flight. Was that normal for that flight or was I lucky to get that?
Do remember at briefing we were told to keep to the timings otherwise it meant the poor studes at the back would need to recalculate all their start shoot figures from the beginning.
