What a poof! There's a decent dual carriageway off the island now and cars are much more reliable these days - plus in any case, the JP Mk 6 is a piece of utter pi$$ to fly! Try it when it used to take nearly 90 minutes just to get past Bangor, there were only 3 channels on TV of which much was in druidspeak, the place was dry on Sundays - and the aeroplanes were infinitely more demanding to fly.
Back in the days of proper swept wing a/c it used to be:
Take-off and accelerate to 370 KIAS (compromise between Gnat and Hunter best climb speeds). Intercept and follow the VYL 100 radial until approaching the desired level off point. Then with about 500 ft to go, roll inverted and pull down sufficiently to achieve level off height, then spot roll back to level flight. Do some GH, then aim for the TACAN dive arc via point Alfa. Start the dive from FL 185, then either join the visual through the I/P or tart about on the ILS. Take-off with full slipper tanks, land after 50 mins on minima with Shawbury, Pershore or Warton as the only available divs. If it was a dual trip, you might get a recovery via the A5 pass which was utter bliss!
