Thoughts with their families and colleagues.

Horrible........ RIP :(

That was entirely predictable, wasn't it?
Darwin Award candidates, both of them. One for doing it and the other for not stopping him.

Bit harsh Mel...but we all have our own thoughts......

10 ft entry height - what could possibly go wrong?

A crowd in front of the hangars. Were they holding his beer? Bet this was not the first time that has been done there.

​​​​Scary but do-able,I should think; until the roll stopped. I know that is obvious. Question is; why stop the roll? All my aeros were/are done above 3000 agl, so would not attempt to answer my own question.

They would have been confident of the outcome going in. Ray Hanna did most if not all his rolling going up hill (always exceptions I know). Did that give him a big margin for error? It kept him alive.

RIP

I thought that, but I'm assuming G/A-LOC.

Looks to me as if they were attempting an aileron roll with an upward vector - but ran out of aileron authority as the airspeed rapidly decreased. Distinct adverse yaw in the initial stages of the roll would have increased drag considerably.

No room to escape from that.

😟

10ft is generous - It looks as if the main wheels were at head height as the pull up commenced in front of the BBQ crowd. That bit was no accident.

I suspect he stopped the roll in a panicked attempt to pull the other way, far too late.
Unlikely to be g-loc, nowhere near enough G nor for nowhere near long enough imo. He might have done better to have pulled up more.

I reckon someone forgot that when starting a barrel roll from wings level half the height of the roll will be above the starting level and half below it.

An aileron roll or even a properly executed slow roll is hazardous enough at that insane level, but stands vastly more of chance of working than a barrel roll. In any case those manoeuvres should never have been attempted without a significant up-line being established before commencing as islandlad pointed out above.

I suspect they did it on the spur of the moment - carried away by seeing all their mates out there

People often smirk on here about all the planning and pre-briefing required these days for fly-bys but that clip shows just why you should do it..................

There are at least 8 pairs of elbows holding phones/cameras up to record what they did. They will know if it was all 'planned' if not authorised.

It wouldn't take much of a risk assessment to establish that this was marginal. That should have stopped them on the run in.

They were within feet of taking people's heads off with the wheels. Would that have stopped them in future, if they had got away with it.

I wonder how many other examples of this are on those phones?

All a sad outcome. If only someone had stepped in to short circuit it in advance.

Salute!

The problem goes back to two things:
1) Prior planning prevents piss poor performance
2) A lack of disciplne or whatever about shining your ass unless you have done it a hundred times and the boss hasn't grounded you yet. There's established demo routines with associated practice and final approval. In other words, no improvising. (having trouble getting my message across, but it will come to me)

Back in the day, when the Earth was still cooling and Orville had just cleared me to solo, one of our new trainees decided to buzz his nearby grandparents. They got to see him attempt a roll and then prang. So for the next few months we were not allowed to fly solo missions unless in a formation. So that's why I had so many formation rides on the docket.

Make no mistake. I did wild and crazy things as a clueless yute. But I am sure there are young folks today that stretch their envelope more than the plane's envelope.

The video should be mandatory viewing for all training courses, IMHO.

We can talk about technique and control inputs and such, but the video seems to show my point "1" above.

Gums opines...

Time and time again we've seen how dangerous a badly flown low level roll can be - sadly, this was just history repeating itself.

Totally agree with that. You have to be very good to do that sort of thing. Not just think you are.

How true that is. Again and again.

Was there a strong cross wind from the left? I have no idea but could that hinder the second part creating a tail wind and changing the dynamics of what could have been 'got away with' before? They were flying north, parallel to the runway orientation and partially sheltered, if the wind was strong.

all the way back to Douglas Bader..................

That hurt to watch, as a former flight instructor. :{

As the roll began I thought to myself "roll rate is kind of low"
and the next thought was
"how many times did he practice this at a higher altitude?"
because it seemed to me that the back end showed a case of 'disoriented pilot'

When I started flying training we would have just gone to the bar and loaded up his bar book which would have been written off at midnight.

Question: it looks to me like some right rudder is applied just before the aircraft starts to roll left - the nose yaws right. I know you are supposed to add top rudder approaching knife edge in a roll but would applying it that early in the manoeuver add a fair bit of drag? Adverse yaw?
