I calculate the probability of an accident with hundreds of drones today at 80%.

Crowds under the drones.

A LOT of moving parts in the sky, operated by digital radio signals.... Jamming from the roads and parking lots.

Who authorized this public safety hazard?

Is it the same idiots who think Amazon can deliver packages by drones?

Tell me I'm paranoid. I hope I'm wrong.

A good thing, they may have very little remote radio control, since they follow a pre-programmed, internally timed, GPS positioned sequence of movements. So maybe some nutcase jamming it won't be an issue.

Anybody know how much "Safe-Mode" or redundancy is engineered into these things? Internal BIT?

I do know that the 4-engine lift rotors cannot stand a single failure without veering at least some. Could be supported with three, barely.
IF they had 5 or 6 rotors I'd say you could have a good limp-home mode to shut down the opposing good engine.....

I assume they've performed a proper FMEA and taken the proper precautions and it happen without a hitch.

Well, one failure mode is: One drone hits another (engine failure maybe), cascades into other drones, u get da picture.
Effects Analysis: Someone gets a haircut & concussion in the crowd below.

Lift rotors are shrouded at least.
Stadium holds 71,795 people.

And you think they haven't thought of this?

Do you just think the risk outweighs the entertainment value?

Security measures at the superbowl are extensive. They have snipers hidden in the ceiling should anyone need to be taken out. I trust the drones won't be an issue.

Snipers taking out errant drones? Sounds real good.

Seriously, those drones are pretty light, and Intel (the drone maker), along with the NFL, is concerned about negative PR or failures.
Another mitigation is a tiny drag chute to slow the drone's speed if it goes down. Self-detecting failure software. Lowering 1/2mV2 kinetic energy would help.
Of course, a failure has entertainment value too, so the NFL might not care. Intel would.

Proven with experience. Another encouraging aspect: Bayesian Logic is reassuring here. If a drone is working nicely (pre-flight checks) right before the show, then the probability of failure is much lower in the next half-hour.

A lot of MTBF calculations assume no immediately prior checks were made.

The same way traffic cameras do, by mail and let you the owner try and fight the issue
 
Small drones? I have a couple swinging 7 inch and my NASA engineer friend is building them with 23 inch carbon fiber props and now the tech is into fixed wing too.
Those smaller drones I find are harder to control

These are about a foot wide. "Intel Shooting Star drones weighs in at 280 grams – less than the weight of a volleyball – and measures 384 x 384 x 93 millimeters. The unmanned aircraft system (UAS) also features a soft frame made of flexible plastic and foam, as well as caged propellers."

Other reports I read does say the drones are in contact with a ground computer via radio signals, so jamming might still happen.
I would guess that only general commands like "Everybody form a bird shape now." is how they work. Once you start each one on a choreography, internal timing could take over.

Yes, you are paranoid. Step away from the internet. Go outside.
I can sympathize, though. I've encountered things that didn't bother most people but really bugged me out. It'll be okay.

Robocop?
 
Apparently the time a model aircraft which looked like a lawnmower being used in a half time Superbowl display went into the stands and killed a man have been forgotten. Shea stadium, 1979

A witness to that 1979 event said: "They were sending those things right over the crowds. I had an aisle seat near an exit, and I had it in my mind that if it came near me, I would run. It seemed so stupid, so sick, to send this thing over these people."

The mass of each of these Intel drones are pretty low, less than a volleyball, and the prop shrouds would absorb what energy there is. It would be hard to actually kill somebody with one.
