Last week, my various inboxes filled up with links to the video posted here, attached to the question, “have you seen this?” How could I not? Shortly after it was posted, it rocketed around the skydiving village like a rubber check in a tile bathroom. I spent a couple of days last week doing intensive wind-tunnel training and we discussed it during our breaks. Suffice to say it’s one of a kind only to the extent that the stall/spin was dramatically captured by a videographer. It is hardly a first and as much as I might wish that publishing it here will make it the last, I know that this passing thought gives futility a bad name. My reaction to these things is often, “the things we get away with in this sport that don’t kill us.” It might deserve firsties for pinning five skydivers inside the airplane during the spin, however.

There’s a lot wrong here related to decision making, judgment and execution of what planning may have been in place. That means there’s a takeaway related not just to skydiving flight operations, but flying in general. It relates to just saying no sometimes. As described in the summary, this appears to be a planned 14-way event or camp of some kind.

To my eye, the first thing that went wrong is that they took off in the first place. The exit was above a broken to overcast layer and although it was thin, the videographer’s footage shows it was right at the altitude where the skydivers broke off to gain some separation for canopy deployment. In freefall, I don’t like being in clouds, being near clouds, or going through them, period, much less with a large group. Deploying with zero visibility invites a canopy collision, especially if the break-off tracking happens in cloud with no visual reference.

When this jump unraveled with people missing from the formatio, the organizer appeared to do the standard pull-it-out-the-bag salvage by signaling for a round formation. He may or may not have known five jumpers never got out of the airplane due to the stall/spin, but they sure weren’t in the formation. Carrying on with some semblance of the skydive made sense because that was the plan and keeping a group together for an orderly break-off is preferable to everyone careening around the sky looking for separation to deploy.  

Jumping in other than perfectly clear conditions requires judgment on the part of the drop zone operator, the pilots and the skydivers themselves. In my experience, the latter have the least ability to make a wise call because doing so means, at best, you may have to go around for another pass or just land with the airplane, usually losing the cost of the jump ticket. Horrors. So skydivers want to exit no matter what and many will. Sometimes, the pilot—who is on the enforcement hook for jumpers busting clouds—just has to say no to taking off in the first place.

This video reminds me of why I don’t like jumping King Airs. They are not a common jump ship, but because they’re relatively cheap, some drop zones use them in lieu of Twin Otters or Caravans. For aircraft, skydiving is a utility operation and Otters and Caravans, with big doors, fixed gear and hell-for-strong structure, are utility airplanes. King Airs are really business airplanes, with smaller doors and retractable landing gear which increases operational and maintenance complexity. One weakness of King Airs is a relatively narrow, aft-tending CG that means the airplane isn’t tolerant of six or seven people hanging off the bars and maybe a videographer perched out near the tail close to a CG station Beechcraft never figured was relevant.  

Skydivers know bupkis about center of gravity. They just assume if they can crawl out there and hang on until exit, the airplane will shrug it off. So the smarter dropzones and organizers who have been through stalls, brief the jumpers on how to do these exits. For every jump, we dirt dive the plan on the ground and set up and practice the exit in a ground aircraft mock-up. Sometimes several times. This is the point where the skydivers in the front of the airplane need to be reminded to stay there until that instant when the outside people are just departing and they can rush the door without causing a stall. In an Otter, you can put six outside and three close in to the door inside and the rest spaced out in the airplane and some forward. It is true that the forward-most skydivers will be delayed diving down to the formation by a few seconds, but better that than being slammed into the cabin walls during a spin entry.

I have been through two stalls in Otters, albeit no spins. I was standing outside for one and departing from the inside for the other. I knew what was happening, even if my fellow skydivers did not. I’ve seen this from both sides. (Sounds like a song.) I’m hardly a Twin Otter expert but I’ve flown enough Otter loads to understand what happens and it’s challenging to deal with it. The usual drill is to reduce power on the left engine and trim up for 90 to 95 knots indicated. When a big group gets out of the door—say eight or 10 perched for exit—the pitch moment starts heading north and it will continue to do that until they exit. If they’re slow about it, you know what’s coming when there’s no more elevator authority left. In this case, the pilot told authorities he reduced the left engine to idle and the prop to coarse pitch, otherwise the jumpers would have too much prop blast to set up the exit.

There’s not necessarily universal agreement on how to fly these jump runs. Some pilots don’t do asymmetric thrust in any twins, some do. For the King Air, recommends flaps and flight idle for the exit, but some power on the right side if the pilot wants to minimize altitude loss. Extreme asymmetrical power seems to be asking for trouble, especially if power isn’t available quickly on the left side if needed.

So skydivers have to be briefed about all this. Hang out there long enough and you’ll cause a stall. Or put too many out there and you’ll cause a stall. And that’s what happened here, along with a rolling moment and enough yaw to initiate a spin. The recovery was quick; it’s only about a turn and a half. I can’t tell for certain, but once the spin stops, there may be some secondary stalling going on during the recovery. King Airs build speed rapidly and the pilot said he wanted to avoid that and may have commanded pitch up too aggressively during the pull out. The pilot attributed the unstable rolling to one engine spooling up faster than the other, but I’m not so sure about that.

The jump organizer can and should have avoided this. The DZO and pilot should have made sure he knew not to put so many people outside and not to keep whoever was out there in place for so long. These guys didn’t discover this on their own. This has happened before and King Air operators know about it. Still, when skydivers get all amped up with adrenaline before an exit, they sometimes ignore the briefing. More than a handful of times, I’ve grabbed jumpers by the collar to haul them back from the door until a bigger group exits.

The most egregious example of this I ever saw was during the 400-way record skydives in Thailand in 2006. We had 410 people in five C-130s. The plan had been for two passes with 200-ish formations on each one, as practice set-ups. These were from 24,000 feet. So it was suggested when the first group exited, the second would walk to the back of the airplanes, pick up the oxygen tubes from the departed jumpers and await the second pass. No, don’t even, said one of the organizers with experience in high-altitude exits. Stay on your butt and stay on oxygen until exit time and then go.

But we did exactly the opposite of that and it was a near catastrophe. One of the jumpers picked up a disconnected oxygen line and became hypoxic enough to fall flat on his back right in front of me. Wisely, the ramps were closed up and we rode the airplanes down—all 200 of us—proving once again that something as risky as skydiving requires unrelenting discipline. The challenge of it is often just learning to think straight with a quart of adrenaline gushing through your veins.

As is obvious here, sometimes you can’t.


  1. Makes for great footage. But one word for it all: STUPID.
    I too drop parachutists from a C-47. I also jump-ARMY STYLE-from 1500 AGL.
    Pulling the power back on one engine when you are already slow is asking for it. Surprised that pilot was able to recover at all. I hope they took his license.

      • Yes, I am too. Remember multi-engine airplanes are not certified for spins, in most cases not even spin flight tested by the manufacturer. As I said in the other thread if you look at the video after the initial spin it took 2 more attempts to recover before the pilot actually recovered and came out of the stall. So yes, this pilot was very lucky to have recovered, fortunately the pilot had plenty of altitude to work with.

    • Just Google “skydivers on a Beech” and click “Images” for an iconic photo of people hanging on to the outside of a Beech 18.

      My favorite one in the series is where the left engine is stopped with a group on the outside… with one of them hanging off the prop blade.

        • Well, I don’t know – I can’t find any specific testing reports by Cessna. Would make for a neat AvWeb article to see if the manufacturers do perform (or simulate) such tests. I do know one of the SkyCourier test pilots is a skydiving instructor and drop-zone pilot so it’s not like they don’t have the talent in house.

          If they’re aiming for the skydiving market (which they are) then it would make sense to test it for what the market will do with it. If they can expand the W&B envelope to allow it then it will make it a safer plane overall. Maybe they won’t specifically ‘approve’ such operations, but certainly test for them. For example, Cessna spin-tested their 180 float-plane even though they weren’t going to certify it for spins.

  2. They even spin-tested the Caravan on amphibious floats–the owner flew our Caravan from Wipline in St. Paul to Wichita as “Experimental”–Cessna put a spin kit on it (jettisonable tail drogue parachute to get the nose down in case it went flat–and the test pilot climbed until it wouldn’t climb any more–about FL 250 (it had the original 600 hp engine) and spun it down from there (FAA regs required it). I asked how it handled the spin–“better than the landplane–the landplane can tend to go flat–the floats are on the outside of the vertical spin line–and the centrifugal force tends to keep the nose down.” (Perhaps the required “tail lets” required for float operations had something else to do with it.)

  3. Is a short-coupled low-tail airplane a wise machine to use?

    Old KingAirs are cheap to buy I suppose, but do the wing inspections – one failed enroute to a fire zone in western US last summer, IIRC was spotter airplane so would have experienced turbulence from big fires.

    Tip: C90 is smaller than B200 which can carry more skydivers, and importantly has a high tail.

  4. Can anyone specify the date of the occurrence in South Africa?

    NOT October 14 which is something else in South Africa’s list of accidents/incidents.

    Or aircraft registration?

    SA’s list is difficult to search in.

  5. The plane was falling out of the sky faster than the people falling out of the sky. It looked like the plane was going to hit someone.
    It is interesting to see just how fast a plane will fall out of the sky in a stall condition. Usually much faster than some planes were designed to fly. Most Cessnas can not fly at 180 mph… but they can fall out of the sky at 180 mph… Always better to fly the plane into a crash than stall.

  6. Full Flaps, tons of aft CG, Asymmetrical thrust, people hanging on the outside, full aileron deflection…..what could possibly go wrong? LOL. Good thing he had lots of altitude to work with……
