If a plane was on a conveyor belt, would it take off?

There is no wind.  The conveyor belt isn't moving air to cause lift.  Just because the conveyor belt is moving the plane's wheels doesn't mean it will fly..   Point the plane the other way and it will.

A belted conveyor usually has two pulleys, one at each end that slightly stretch the belting to maintain the belt's position and to provide increased friction between the belt and the pulley.  One of the pulleys is driven, usually by a motor, leaving the other pulley as an idler pulley.  The motor rotates the belt around the two pulleys.\n\nBetween the pulleys is usually a smooth, wear resistant surface that the inside of the belt glides across.  This surface supports the belt and whatever may be riding on it, but has a low friction surface so the belt slides easily across it (think of a tablecloth on a table).\n\nSome belts will have a small raised section on the inside of the belt.  This helps improve the belt's tracking across the pulleys.  Without it, the pulleys need to be exactly parallel and belt in in good condition.  Otherwise the belt has a tendency to eventually roll off to one side or the other.

defo invisible...cos u could also fly. Nobody would c u gettin' on a plane! \n;-)

Nope...force is what you are looking to determine.  Force equals mass x acceleration.  The fly would have to travel MUCH faster to have any impact on the train.  Also, the fly, once it made initial contact with the train, doesn't decelerate all at once...parts of it continue moving after other parts stop, and some parts start moving in East and West directions...SPLAT!

The "black box" is actually bright orange, so it can be found easily.  It's made of quarter inch thick stainless steel, while the skin of a plane is made of aluminum about 28/1000 of an inch thick.  If the plane were built of materials even 1/10 the strength of the black box, it could never get off the ground.\n\nEven if you could make a plane out of concrete and steel I-beams, and somehow get it to fly, if it hits the ground at 100mph, it's going to get crunched, no matter how strong it is.  That energy has to go *somewhere*, and a good portion of it will go into the plane's structure.

It would depend on the motion of the elevator, would you care to be more specific?

There is nothing aerodinamical that will prevent airplanes from flying directly over the pole, yet airlines in routes such as New York-Hong Kong take a small detour when going over the pole.  The reason is not to mess with avionics and guidance systems (at the pole all directions are South and computers may react in unintended ways). The concerns are similar to those about the year 2K issues back in the year 2000.

Yes, but only if they're passing through.  An extended time in the Belts would be lethal even in a spaceship, unless the craft were heavily shielded.

The air inside the vehicle is moving the same speed as the vehicle. To the fly it's still air, unless a window is open, then the fly may not be able to fly normally.

The plane is actually following the curvature of the earth, which only seems to look straight - exactly the way ships do.\nIF it would follow a geometrical straight line, it would actually increase altitude, leaving the sphere of the atmosphere, and make it look like a perpetuous climb (gain of altitude) to a LOCAL observer ...\nBut the so cold level-flight, is a question of keeping altitude, or keeping touch with a certain air pressure, which means a constant distance to the earths center of gravity, making the path a curve...\nSo, a plane is not flying a straight line - strict geometrically (and GLOBAL) speaking!

why not? just because they are going over the speed of sound does not mean that they produce no sound themselves.  if you were standing still and it flew overhead, the sound would be "out of synch" with where you think it should be (from the plane) and where it comes from (behind the plane) but it would still make noise.  Also, if you were traveling alongside of the plane, you would hear it just fine.  Sound would still travel at the same speed relative to the moving bodies.\nno! going over mach 1 does not mean you would not hear sound.  You are not right in thinking that.  read my anser again, cowboy//

Since the plane flies by producing thrust and thereby offsetting its weight, the weight in flying state is zero. The mass remains the same as it was on the ground.

ok, it would freeze quickly (not explode-it is made of solids and liquids, which don't expand in vacuum). But for fun, assume it doesn't freeze or die of hypoxia.  Since there isn't any air, there is nothing for the wings to beat against, so it would flap it's wings and just stay in the same place- The motion of the wings might cause it to start rotating, though-so I would imagine the fly (which is a magic fly that doesn't dry up, freeze, or need oxygen) would just spin around in a tiny circle right where it is.

Most modern airliners don't need the pilots to land these days, is mostly done with ILS and computers.  Pilots are mostly there to take over if things go wrong.  Without the computers however, a civillian with no training would likely wreck the plane unless being specific instructions from air control.  I'd not trust that person though....

A plane would only have to travel at approx 1000mph to go around the Earth in 24 hours.  Some supersonic jets easily travel that fast.  Throw in time for slowdowns to meet with tankers and landings to refuel.  I believe that it can be done.  I'm surprised that the government didn't have the Sr71 attempt it during its career.

Yeah, it's not a jet where air is pushed out.  It is a chemical reaction where chemicals are burned and thrust out the back of the ship.  It's like if you were floating as still as possible in zero G and blew air out hard.  you would move in the opposite direction.  If you held a little bottle of any gas under pressure and opened it, you would move.  Same basic principle. It's not pushing against the surrounding air, it's just pushing away from you regardless of whether it's a vacuum or in air.\n\nIn fact, in air you would get less of a push than you would in a vacuum.

Ok, first of all the jet would stop working once you left atmosphere - but ignoring that for a moment and assuming you were in a craft capable of going 500mph:-\n\nWell at about 2.7 billion miles away, approximately 616 years.\n\n\n\n**update** Phew, so pleased to see that someone else concurred (+/-) 1 year, I suddenly thought I might have been out by a factor of 10 :)
