Yelling at each other about 9/11 (Split from the "How has Trump pissed you off today" thread)

Note that proportionally, a soda can’s walls are mych much thicker than an airliner’s are, too.

Man, the rabbit hole is getting deeper. One thing I didn’t see in the sky for days after 9/11 was chemtrails!

Is the airliner on a treadmill?

Or rabbits! I didn’t see rabbits in the sky!

Not to mention that 7’s debris pattern indicated it split apart as it fell. Most of it crossed the street and fell on the CUNY building at 30 West Broadway; the rest slid into the Verizon building next door. Certainly not “one neat footprint”.

It depends of whether the airliner is on a treadmill.

Some person on the SDMB, I don’t think Biffster, said that the planes would bounce off of the buildings and just fall to the ground. (IT’S TAKING LONGER THAN WE THOUGHT)

Might have been the same person from the IMDb. We’ve had at least two pushers of “truth” from there; they didn’t last long.

Would they make an amusing boing sound? Or, more of a plunk? Or, maybe a bonk sound, like a coconut?

I guess it’s hard to accept that people are such fragile creatures. We are though. Planes are fragile too.

In Civil Air Patrol, once brought back all that could be found for a Cessna 172. It fit in the back of a Chevy short bed pick up. The engine and tail, sort of ‘intact’ (my bother was on that work)

It’s funny that all these misconceptions seem to come from the fact that they don’t realize that both planes and skyscrapers are basically empty shells filled with air.

Human beings are terrible with different scales. Comes with evolving for survival on the veldt.

Planes and skyscrapers might as well be 100 foot thick granite walls to a person. But not so much in the grand scheme.

But when I was at Universal Studios I saw an airplane that had been shot down by aliens and it was far more intact:

Yeah, in Civil Air Patrol, we didn’t look for airplanes, we looked for odd, unexplained disturbances on the ground. A few downed trees was also a good clue.

That took me a few beats to catch. Good one.

Also with different contexts. If you’ve developed the intuition to estimate horizontal distances, you’d think that it would translate to vertical distances. But it doesn’t.

If you’re looking down into a hole, the distance looks much larger than the same distance looking along the ground. You need to develop an intuition for vertical distances separately.

Well, they were Boeings.

Noice.

No need for apologies - that was an excellent explanation of some of the points I had missed and a welcome addition.

This discussion has, tangentially, sent me down a rabbit hole of wondering what happens when/if the Leaning Tower of Pisa collapses.

I mean, if there was ever a building that intuitively LOOKED like it ought to go TIMMMBERRRR and tip over describing a graceful arc before hitting the ground horizontally, that’s the one.

But, for instance, earthquake simulations like this one make it very clear that even the LTP would essentially just collapse straight down. Even a heavy medieval stone tower is mostly an empty shell filled with air.
