Should note that's a 707 that Tex Johnston rolled, not a 747. I'm not aware of any barrel rolls performed in a 747.

It wasn't even a 707, it was a prototype model 367-80. There were some unusually significant structural differences between the prototype dash 80 and production 707's, for example: > The 132 in (3,400 mm) wide fuselage of the Dash 80 was large enough for four-abreast (two-plus-two) seating like the Stratocruiser. Answering customers' demands and under Douglas competition, Boeing soon realized this would not provide a…

It's in the wikipedia article, but just want to call something out: That particular airframe 367-80 is in the Air and Space Udvar-Hazy museum at Dulles. It is gorgeous.

The 747s first airframe is at the Museum of Flight in Seattle, and you can _go inside it_. https://www.museumofflight.org/aircraft/boeing-747-121

Interesting. I often feel safer in smaller (but not too small planes), where I don't see the wings visibly flapping. Something like a A320 or a 737. With 747s the wings flap up and down quite visibly in turbulence, and you can even see the fuselage twisting if the curtains aren't closed between the sections. There's also just the wall thickness to mass ratio. You ever notice that you can crash toy RC cars all you wan…

Any plane at 500mph is tissue paper if it hits something. If you haven’t seen the wing flex in a 737 or A320 you aren’t paying close enough attention. It’s very obvious during the takeoff roll as load is applied or during any moderate+ turbulence.

Sure, but a commercially-sold 1:500 plastic model of the same plane crashing into a wall at 1mph won't be tissue paper.

Similarly, ants can lift 100 times their own weight and survive having 5000 times their own weight placed on top of them, but it's quite impossible to for a human-sized mammal to do the same.

This was almost certainly drawn out by hand, waypoints (lat/lon) and turns were plotted and then inputed into the flight management computer, and there is a good chance the plane just flew itself as told. Although given it was flown at such a lower altitude below 15k feed near Moses Lake (which is where Boeing does a ton of testing at that airport) it's possible the pilots hand flew this by following a pre-plotted ma…

They could also just spoof the ADS-B data right?

Every complex project lives and dies by a relatively small group of true believers. From the outside, we don't know who they are, but sometimes we get a glimpse of their passion.

I think it's more that most people are basically trying their best and that includes managers and top brass. Sometimes we get a glimpse when that shines through from the whole group.

I don’t mean to be negative, but most people certainly don’t try their best. Many are only working for the paycheck and don’t attach their sense of success to their professional output.
