You can see the horizon line at approx 6 kilometers on open sea. Thats roughly 4 miles.

The best way to illustrate your question, is to view the laser coming out of Greenwich Observatory. As light doesn't bend, you can clearly see the distance between ground and laser increase, and I'm sure I can't even see for 14 miles, let alone 140.
To answer to your question, no, you couldn't stab someone, as your knife/sword thingy would probably be half a mile in the air, rough calculation

I recommend curving your knife

- wtf how lame!! the plane is moving forward. the only difference is that the wheels will spin twice as fast!!Projectile

the correct answer is: the treadmill cannot slow down the plane, unless the friction it exerts on the wheels is great enough. the wheels will simply spin twice as fast and the plane will move the same distance forward as it would have on solid ground and take off when it normally would.

where do you store this knife?

better question: if you put an airplane on a treadmill, and accelerate the treadmill backwards against the plane at the same rate that the propeller is moving it forward, will it take off?
- Oh don't you fucking dare - this place inverted itself when we had that as a thread.detritus
- no it would not take off. you're actually stationary, so air is not flowing above/below the wing. no air, no lift.bulletfactory

Don't you have an elbow?

If I were the man you were stabbing I'd take a step to the side then laugh as you couldn't pick the sword up.

I suppose the first question would be "Where is this man?" If he's beyond 140 miles, any talk of curvature is redundant.
