No one ever identified the thing on their person that proves Special Relativity.

No, it would not. The way the question is worded prevents the plane from achieving any horizontal velocity. It is the specifics of how the situation described by the question could exist that brings in ridiculous conditions. The plane would not take off.

It wasn't the lithium batteries? (someone suggested that many pages back)

Interesting thought exercise. If one were to pass an event horizon and someone from a vantage at rest wrt the black hole could observe you. You would appear to them to disappear at nearly the speed of light. While, were you able to maintain cognition, you'd experience a lengthy, perhaps lifetime long, descent where the gravitational difference between your head and feet would cause you to stretch almost infinitely from head to toe.

Well, with normal conditions, as stated waaaay back at the beginning of this - yes it would, because it has nothing to do with the wheels and normal materials wouldn't be able to counteract the thrust of the jets through the wheel, no matter how fast it turned.

Anyway, this has degenerated into "Yes it would", "No it wouldn't", so I'm outa it.

New topic:

1 = .99999999... repeating infinitely

True or false?

GPS, the locators have to make the adjustments for relative velocity between the locator and the satellites for the location equations to fit.

True.

1/9 = 0.1111111.....

1 = 9/9 = 9 X 1/9 = 0.9999999999.....

We've argued that to death before already, if you can believe it.

How about

1/2 + 1/3 + 1/4 . . . . to infinity approaches infinity

but

1/2 + 1/4 + 1/8 . . . . to infinity approaches 1.

You guys are still going on this?

Wasn't it agreed upon that the initial question wasn't worded correctly?

Actually, the limit of .999 inf is 1. But it NEVER =1.

I've never really looked into it before, but I found this. As for me, I'm going home.

No, not really.

I've heard .9999 repeating = 1 and that repulsed so much I gave up on math for several years.

And also that pre-calculus was so incredibly hard and class usually ended up with me drawing dark pictures and crying.

It travels at C away from you, doesnt matter that you were traveling at C to being with.

C = speed of life

It's an easy proof, which MagicHef already did (spoilsport).
