luckily it wasnt at the air show either, could of been devastating if it went into the crowd.

Lucky indeed... Anyone know his lotto numbers? ::) ::)

Glad he decided to bail when he did :y :y

Despite sophisticated technology, plain old gravity wins - sobering lessons on the fragility of those things we take for granted and toy with at our peril.

It's good that the pilot survived 8-)

Saw that on Sky news this a.m. Lucky chap.

He left it very late to get out. Do pilots still suffer compressed spines etc from using an ejector seat or have they improved them from a few years back?

Not really ... he was doing a "high alpha approach" which is common at airshows .... simply put .. almost balancing the plane on the jet thrust, very little "lift" being generated by the wings at all, at around 100ft. Crowds like it as they get to see the aircraft at slow speed with lots of noise ....

Looking at the "stills", or pausing the video, it can be seen that one exhaust cone is fully open, the other pretty much closed. The cones move automaticaly depending on the thrust produced ... so it looks very much like he had an engine failure and lost all thrust from one engine (the one with the closed exhaust cone). As he is flying below Vmca - Velocity (minimum control airspeed) the flight controls (ruddder/aileron) do not have sufficient airflow over them to generate the forces to actually control the aircraft, which is why it turns then starts to "wallow". The pilot would know about the engine failure almost instantly, and from the pictures he ejects about 4 seconds after it occurs. About as long as it takes to realise "now or never" ..

As to back injuries, the modern pilot "lies back" in his seat much more horizontally than of old, to help conteract G forces. So on ejection as the seat goes with him the forces are "spread" along the back rather than being straight down it .. if you get my meaning. he'll still have some compression problems and a very sore neck I expect .. but should be OK.

Should think his adrenalin reserves are a bit low, & his colon will have a few kinks in it! Glad to see a good outcome :y

An amazing photo of the incident ... you can see the difference in the nozzles.. and the pilots head is in totally the wrong position .. thats why he'll have blackeyes and a sore neck ..  but I guess he'll be happy to be breathing  :y :y :y

even there is no failure you will be out of fuel at the end.. ;D

so gravity always wins sooner or later..

too risky.. I would personally try that with a vstol like harrier , at least you would have a nozzle down the plane that pushes you up :-/

those planes are not designed to fly like that, at high altitudes (without engine failure) you may try that as there is plenty of distnace to cover up but just some meters above the ground , thats stupidty.. :(

Probably not any safer in a Harrier, TBH. Single engine flat out with little cooling and a relatively high chance of foreign objects. In this type of aircraft if the engine fails you will most likely lose the aircraft regardless of the phase of flight. They don't make good gliders even when they have flying speed.

Engines in planes. Tsk. It'll never catch on. ::)

Pleased to say the pilot is in very good shape considering .. :)

Yeah .. whoever took it had all the right kit and the luck needed to get a "once in a lifetime" shot ... and with the number of newsagency's carrying it I guess he/she is making a few bob out of it as well  :y :y :y

 I wish ......

Thats an amazing photo!!!!

But cant help wondering why the health and saftey lot didnt move that 200ft speaker out of the way,It all seemed to be going fine until then ;) I know fighter pilots are good but to make them fly through speakers.......... :) :)
