That went about as well as expected, possibly better than expected if they lived to see the footage.

:shock: As close as it gets , brilliant example of just how quickly things can get out of control in IMC. Yikes !

:shock: :shock:

Why would anyone fly a glider into that kind of weather?

Also, what is that annoying whooping noise/alarm that rings in the background the whole time?

I don't know much about gliders so honest question.

The Wooping noise is an audible vertical speed indicator (VSI).
The higher the pitch the higher the rate of climb.
Allows the pilot to look around instead of staring at the instrument panel all the time.

With all the threats, decision making, and stupidity aside, this is one of the worst stick and rudder (lack of coordination) examples I've seen.

Have a look at the 4" piece of wool on the front of the canopy. When there is no propellor slipstream to effect its purpose, it's a very valuable SLIP and SKID indicator, and this guy's feet are very lazy. With gliders, you need to lead the turn with the rudder - and his feet are firmly planted, which, in turn, contributed significantly to the spiral dive.

The best hand and feet flying coordination route (by far), is to learn on Gliders and Taildraggers. Taildragger pilots will never relax the elevator backpressure after touchdown (in a tricycle undercarriage), and therefore can never bounce - nor wheelbarrow.

Unfortunately, many parts of the aviation industry nowadays have been dumbed down, and the by-product is that skills and aptitude are now lacking :shock:

However, I am glad and relieved they survived this ordeal.

Please be safe guys, Darryl

Totally agree with “darryltarr”. If you look closely, the pilots left knee does not move, relative to the brake lever. No rudder input.

Here is the link to an analysis of what happened to these pilots by a gliding instructor.

Well, no IFR instruments, no charts (tongue in cheek)... someone is in die Scheiße! They are ferucking lucky they lived to tell the tale.

Also a CRM clusterfok going on there where, Its evident that perhaps there was no preflight briefing or if there was one it didn't cover emergencies because from my point of view those points are only being made clear during the emergency which doesn't help much.

Very greatful for the explanation video because the first time I watched it this morning I wondered if any young trainee would even be able to understand what went wrong there.

So they were expecting to come out on the windward side of the ridge, but succeeded in coming down in the lee rotor, having to do a downwind canyon turn to escape in downflowing air, entirely possible to stall the aircraft even with nose pointing 20deg below horizontal. They would have needed to shove the nose down 45deg to escape. I would say the one noticing & talking about airspeed was the calmer of the two, while aiming the nose down a gulley.

The yawstring at the beginning is nothing

I would say, that instructor should have had his flying license pulled, for life.
They were very, very lucky to get out of this alive.
There are a few markers on mountain slopes in the Western Cape where glider pilots were not that lucky.
The Worcester guys can elaborate.....

Flying as he was on the windward side of a ridge with a reliable escape to the right was ok and he would have known that to the left he would have had Imc and sink .
Watching his flight path you can see where he went wrong by going left behind a developing cloud . At that point he should have turned right about 30 deg. to stay on the windward side .
From there he was trapped. Just by luck and a bit of skill they were able to dive down the leeward side of the ridge and had the collective insight as Thermalator said to keep the speed up.
About 5 years ago we had a glider crash with fatal results in Natal under similar circumstances ie. Stalling on the leeward side of a ridge.
