The conveyor belt thread.

It's like why do they show you how to fit life jackets in the event the plane will land on the sea?

Whilst I would not be absolutely certain it would never happen I understand the likelihood of a plane landing on the sea is quite remote.

Apparently for a plane to remain airborne it needs to travel at a high speed, if it falls below this speed it will just drop out of the sky and disintegrate on impact. However if the pilot manages to glide it down such that it is doing the required speed to remain airborne at the point it touches the sea.... It will again break up on impact.

Sorry if anyone is flying anytime soon.... I'm off to Stockholm on 6th November... and there are no worries here.

Think Capt. Chesley B. Sullenberger might disagree with you!

Good spot MD.... It would be interesting to compared how many attempted ditchings were successful as opposed to total failures.... Clearly there is a benefit in paying attention at the start of your flight... So take note and Pay Attention!!!

Anybody who thinks the plane would not take off is as thick as fucking mince.

Not really. It's a pretty counter-intuitive and often badly-worded puzzle.

This is the question asked: "If a plane was travelling down a giant conveyor belt at 180mph, trying to take off, but the conveyor belt was travelling at 180 mph in the opposite direction, would it be able to?

You would still have the thrust of the jet engines at the back."

IMO, the question is pretty straightforward. The jet engine/propeller provides the forward movement by pulling against the air - what happens on the ground is irrelevant if the wheels are free to rotate.

I believe it would fly
I believe it would touch the sky
everynow and oh fuck it

yes it would take off

If the plane remains stationary relative to the surrounding air then there is nothing to provide lift as there is no differential air flow across the wing. If the plane is moving at 180 mph relative to the conveyor body than it will take off.
