You would be surprised if you saw the bunkers all set for our so called leaders and their families, they could last 5 yrs underground, maybe more.
But you will never hear or see anything about it.

 

[boo]

No

Agreed…especially about the Super Bowl… Denver has seen much better days than they’re going through now…

No

why?

Yes. The plane will take off. The engine thrust doesn’t have anything to do with the wheels turning. The engines push the plane forward regardless of the friction(or apparent lack of friction the spinning wheels and conveyor belt simulate) since they are pushing against essentially a wall of air.

I disagree. I believe they will not take off because while what you say is true the issue is you won’t have lift on the wings because the air is pushing through the jet engines but there is no lift on the wings as there is no airflow over the wings and flap area. Without lift on the wings the plane cannot take off.

When in a storm all of a sudden the plane can drop several thousand feet then catch. The engines were still running but a heavy wind removed lift and it had to be restored.

why?

No lift. Wing must move through air for that to happen. Wing has no idea what wheels are doing regarding lift.

 

[Hippie420]

True, but backwards. The wings don't have to move through the air. The air has to move under the wings. Small planes must be tethered in a wind storm or they'll be gone. Nose into the wind, they'll go up, albeit not for long 'cause they'll crash unmanned.

Nothing is stopping the plane from moving forward. The thrust pushes the plane(and since the wings are attached to the plane) forward creating lift. Wheels do not propel the plane forward. The engines do. Sea planes can take off from water even if the water is moving in the opposite direction of the thrust.

This may be hard to accept but when flying in a plane that crash part makes a big difference…to most people.

I get what you are saying. You could put a battery of jet engines in front of the plane and move them to create lift but as soon as it’s out of the bubble it’s scrap. However it would, technically, for a few seconds take off which makes your observation correct

True the plane can move forward from engine thrust however to fly those engines would have to tilt to provide thrust at the correct angle and provide lift until at a speed where the engines can be set for direct thrust as the wings achieved lift.

As for the water it provides nothing but a runway due to the ski effect

 

[dogster]

It will just keep rolling in place due to no thrust and no thrust means no lift.
Why cars get need wings to create downward push.
The thrust creates the lift.

I thought airplanes need lift , not thrust?

if the belt and wheels are moving at the same speed , there is no lift , no?

under the wings yes and the lift is on top of the wing , no?

 

[user 60606]

plane never takes off, . There are 28 Cape cobra and 40 black mamba snakes loose onboard which creates an anal sphincter vacuum from the 233 humans inside collapsing the fuselage ...

The engines provide linear thrust. That causes the plane to move forward. The forward motion of the plane and wings(those provide the lift not tilting engines) moves air over the foil to provide lift. Wheels on airplanes allow the plane to roll forward(essentially a low friction surface the fuselage can travel across to reach the velocity that the wings need to provide lift). The conveyor belt would need to travel backwards fast enough to cancel the velocity the forward thrust provides in order to keep the plane stationary. The speed of the wheels and conveyor belt are irrelevant.

Thread drift going on here for sure. Are these really your random thoughts? Such great minds I know around here wow. Someone help me smoke this joint…
