Lots of unanswered questions when I read the Special Bulletin. Does anyone know if the AAIB are to do more investigation of the circumstances of the flight (rather than the post-incident download and analysis which is what they seem to have concentrated on so far)?
It would be interesting to know whether the site was lit.
Apart from a thankfully different outcome at the very end, this incident feels uncomfortably like the G-BYPA AS355 accident back in 2007.
Air Accidents Investigation: AS355F2 Twin Squirrel, G-BYPA
We still don't seem to be learning from our history.
