Big problem is the use of autopilot navigation locked to the GPS route.. this pretty much guarantees that you will fly right below the wake of the above plane on the same route! (Before GPS it will be very odd to flight exactly the same path) ..

Eh. e.g. the north atlantic tracks have been around since the 1960s. GPS wasn't available to the public until Korean Air Lines Flight 007 in the 1980s.

This is a reminder that the announcement that you should "keep your seat belt fastened at all times when you're in your seat" isn't just something someone made up. It's a small price to pay in case you ever encounter severe turbulence en route, but it might be one of these things that most people don't realize until it happens to them. Hitting your head against the cabin ceiling can seriously put a damper on your tri…

True.I would think this would be more of a problem for people from US states where wearing a seatbelt is not mandatory.

In other parts of the world (with more sense) such as Europe, Australia, we're conditioned to always using it due to strict enforcement and as such it's not such a novelty.

When I was in single digits, my mother and I were coming home from an international flight and the plane was struck by lightning. We lost a bit of altitude (felt like a TON of altitude subjectively), and yeah... it was a damned good thing we'd all been told to keep those seatbelts on. It was literally the difference between seconds of terror, and someone being seriously injured.

Yeah I'm pretty sure that's the first rule that goes out the window when you're on a private jet.

There's a reason that people with money and power don't always experience good outcomes. Sure, you can do what you like on your jet, and therefore expose yourself to risk that most people never experience. Likewise skiing off-piste or a number of other equally silly activities that you can do, but absolutely shouldn't.

While I agree with the general sentiment, to be honest there are easier solutions here. They could've just turned on the sign as soon as they saw the A380 so that people could fasten their seatbelts then. And then turned off the sign when the threat was gone. You don't need a cannon to kill a fly.

In the 1-2 minutes between this thing booming past them, and being sent into a spin... you want them telling people to buckle up? That doesn't seem like the easier solution; it mostly sounds like a way to have people still hurrying in the aisles when it's too late.

In a car you usually fasten your seatbelt all the time so that you don't have to guess when the risk is going to occur. In a plane there's no reason not to act the same way.

Sure there is. The chances of dying in a car accident are around 1% whereas the same in an air accident is, like, 100x less likely?

It's like how you wear a helmet when you're in a construction zone but you don't wear a helmet when walking around the city despite the nonzero chance that something might fall on your head. (Or do you?)

Earlier quoted context omitted.

Wings generate lift primarily by deflecting air downward. There is an area of low pressure over the wing where air is taking a longer path than under the wing, but that is only responsible for a small fraction of the lift.

"Longer path" has no bearing on reality. A flat plate can generate plenty of lift even with both sides the same. It's also hard to define "path," as the air starts convecting well ahead of the wing in subsonic flow.

NASA has even published on this issue https://www.grc.nasa.gov/www/k-12/airplane/wrong1.html

Or, as with cars, just be in the bigger car. Another a380 would probably have shaken off this encounter. Size, and the flex that comes with size, flattens out these things.
