Design flaw or did the crew simply unreasonably exceed the boat's design parameters?

Didn’t seem like a design flaw. Watching it, it seemed like a poor tactical decision to make a risky maneuver combined with an issue with the leeward runner not letting the sail out. Before making the tack, someone on the boat (the tactician?) stated that it was going to be a difficulty maneuver, and seemed to warn against it. The other issue is that the sail wasn’t able to run out when needed. Not sure whether there was some kind of mechanical failure of the mechanism, or human error.

Yes, that leeward running backstay remained tight and as the helmsman bore off to head downwind, the main could not go out further than the backstay would allow. Boat got way overpowered and went airborne. Had to be one hell of a jolt when she landed. No seatbelts and airbags in that rig so I'm guessing that the boys are sore today. Good thing for the helmets and flack jackets.

Don't think that runner is anything but mechanical so I assume somebody didn't ease it - probably as a result of the back to back maneuvers, tack followed by bearing off.

The boats are like fighter airplanes now, radically unstable, they need to be sailed with a certain level of aggression and tenacity. These are definitely not pleasure boats.

The current AC boats are in many ways similar to older design stern steering ice boats. Watch this video of a stern steering ice boat capsize, looks much like American Magic capsize:

Here is a good video from NZ Herald discussing the incident and aftermath.

Yeah, that would do it.

Not even close to the same thing, but we raced our 30 ft. Pearson P30. She'd been significantly re-fitted by her PO to be closer to a race boat than the racing cruiser Pearson had designed her to be.

Being a relatively stable keel boat with a 5,000 lb. keel, she was unlikely ever to suffer a broach or blow down, much less capsize (unless we ineptly flew a kite) but, if we got certain maneuvers wrong in heavier air, we could certainly have lost helm control and/or damaged things (or people). Came damn close a couple times.

My Pearson 30 story. I've never seen a bottom so big from up close and personal. We were racing our J24 at Grand Lake in OK and right at the start, close hauled and staring, a huge puff comes in and we handled it just fine but the guy driving the P30 Flyer just to leeward of us did not. She rolled up and rounded up to weather which we had to head up to avoid. When she rolled up we could see damn near to the keel. That was a lot of bottom exposed right over my right shoulder.
