So would it be fair to say the little wobble prior to hitting the ground wasn't an effort to try and alter his course, it was the aircraft in the stall and literally falling out of the sky with wings doing what I've seen models do just before it goes in?
I'm obviously speculating just like others but yes, to me it looked like it was buffet as the wing stalled - on the far side of the CL alpha curve - in a max and decreasing lift, high drag state.Glad to hear he's out of the coma.

There's a Hunter documentary on Youtube. In it is an interview with a now-elderly test pilot who arrived to demonstrate the aircraft in Europe (Switzerland I think) and started the display by spinning the aircraft to a pre-determined height then initiate recovery to pass low over the airfield. Upon counting the turns in the spin, reaching his gate height and recovering the aircraft he found himself diving vertically at the local landscape with the fields much bigger in the windscreen than he expected. He hadn't set the altimeter to QFE before starting the display...
I went to a RAeS lecture by a Hunter test pilot and he described just this, seems the audience were suitably impressed by the performance and ensuing low pass after the manoeuvre - only he knew how close it was... Fascinating guy who talked about a fascinating aircraft that had some nasty habits so pilots were not permitted to do some certain maneouvers in service. None really applies to what happened this time though. HarryW said:
All the conversations I've heard between controllers and fighter jocks it has always been QNH, which gives them Altitude AMSL. QFE is height above a the reporting station.....
Which is why you would expect the pilot to set his altimeter to QFE before starting his display over the airfield.HarryW said:

Civvy pilots set QNH for en-route flight, thus all (hopefully) aircraft are using the same altimeter setting. FL20 for example (or any FL) can vary by hundreds of feet, depending on barometric pressure at the time. A pilot will be given QFE when contacting the approach controller so that circuit height (or descent profile/rate for commercial stuff) can be judged, relative to height of the airport.Eric Mc said:

Oops! over 30 years since I last flew (as a PPL) Perhaps I can claim a senior moment in mitigation?

I heard yesterday that he was transferred to another "undisclosed" hospital? Not for his protection surely?
I read that as well and I imagine it is for his own protection, from the media as much as anything I guess.Would not like to be the person who tells him what happened.

We stick on QNH for all ops in our company, even when operating in China/Russia where QFE ops are the norm, we convert to QNH. Btw.Mabbs9 said:

Yep in the airways, anything above transition alt is on 'standard' so all refrenced to 1013 and a bit. CIS and China complicated things by using metric with QFE. We still convert to imperial and QNH, it just means an airway is flown at 26400' or 31500 etc. Anyway, bit off topic.

And how do you know accidents won't happen again?

Right. Either someone deleted a post or Eric's lost it big time.And how do you know accidents won't happen again?

Guesses on a postcard....
The post also suggested 'We told you so'
Not sure who it was or what he was on about and Eric's response was fine
