It’s been a long time....

But if I remember, drop speed was 90 kts. We used to slow it up, the when ready for the drop, pull the left throttle to idle, to reduce the propwash for the guys on the way out.

I’m thinking this guy was trying to get it as slow as possible, to allow more of the guys to get outside and hang on. And then he lost concentration/ was focused on looking back or some such, and the next thing he knew, he was going over.

I had it once, while testing one post major mantainance. It was required to fly an approach to the stall, buffet. Before we were nearly ready for it, it dropped a wing, and departed. Table Mountain looks spectacular when viewed upside down.

If it wasnt deliberate the bombs were very lucky. I once read that you must always jump inside the spin.
The aircraft moves away from you. Outside it will kill you.

I am with you 100%, Diesel, that had to be accidental. No sane pilot would deliberately risk spinning into the meat-bombs.

I am sure this is not the first time that a drop plane has spun due to masses of parachutists trying to see how many they can stack on the outside of the airframe before they let go.

Maybe the pilot felt that if he let the spin continue for an additional turn, it would pull him away from and not closer towards a potential collision with one of the parachutists ?

Slight hijack:

I dunno how to embed YT video´s, but this is one from Boeing test pilots stalling and then departing in a B717/MD95.

Interesting that the American test pilots don baseball caps and casual wear vs orange overalls of their European counterparts.

Wasn't there an Atlas Angel that spun during a para-drop a few years ago. I remember seeing the control surfaces and they we exactly where you would expect them to be entering and maintaining a spin. It went through 8 or more rotations before recovering. (I also recall a video of a BN Islander doing the same thing)
I'm pretty sure the Dak driver in this thread did not spin on purpose. Over confidence perhaps?
When that many people move aft for the exit, the cog changes. Hang a few jumpers outside, retard the left throttle to be "nice", and the holes in the cheese start lining up.

Heck going into an incipient spin like that in such a big aircraft must be hair-razing.

No Parachutes doned either
