In answer to your question....
The AAIB Bulletin is now complete and scheduled for publication soon. Confidentiality precludes me saying anything more.
The CAA is engaged in an investigation of the allegations ( mostly made on PPRuNe) and I have cooperated fully and openly, sending them a copy of my original report to the AAIB, giving a host of evidence and answering every question they have asked. I do not know when they will conclude.
In the meantime I have had some very good correspondence (mainly started through the publicity from PPRuNe) with some serious pilots and instructors curious about the pancake technique. It seems that it was a part of the ops manual (just as I described it) for the Burma campaign, but the instructor who got in touch with me was completely unaware that the manoevre was frequently used in WWI and had been immortalised by Capt. W E Johns in the "Biggles" book! The RFC bequeathed it to the RAF.
My Bridge partner, Alan Simmons, was a Mosquito navigator in WWII and described to me after the event the many who tried the pancake technique after engine failure over the forests of Norway, Belgium and Germany. Most died instantly but a few survived. The CT, with its highly safe cockpit cage; its wonderful aerodynamics and its carbon fibre construction, made the landing a lot more survivable than a ply-balsa Mosquito carrying the weight of TWO Merlins and a glide ratio and speed that made a brick look good. (HIS words before you Mossie fans protest!).
Thank you for your continued interest and I hope that you will find the AAIB bulletin interesting and a help to safe flying.
