Just going to leave this here

No. The helicopter does not go along with the train, generally speaking.

If the air were replaced with water, the copter would go along with the train, generally speaking.

The reason for that is the force that the water exerts as drag is orders of magnitude greater than air.

It has nothing to do with pressure. Also, given a sufficient moment of acceleration it hits the wall in the water.

 

Are you speaking about a copter that is already moving along the same vector as the train and they both maintain that vector or a copter that is hovering relative the ground and then the train moves?

 

I'm talking about the doors are open while people load the train, dude flies his helicopter in there, the doors close, and the train takes off.

 

Yeah, well in that case the copter hits the wall.

The reason things don't go apeshit in an airliner is that they are flown smoothly and you are seated for when shit ain't smooth.

Pressure isn't really a factor in this outside of extremely dense air and exceptionally high acceleration forces.

 

That's what I said back in the very beginning.

Even in the picture in the OP it says "the helicopter enters a resting train and hovers, then the train moves".

 

Correct, it will smash against the wall unless the pilot – operator counteracts for the motion and sets the helicopter in a forward moving motion to keep the same distance to the wall while staying at a set distance to the floor, until the train Has reached its targeted speed that it’s not required anymore to compensate positive or negative acceleration

 

Pseudoforce

 

So, what if you take a 2 oz fishing sinker and a 40lb dumbbell to the top of the tower at COTA and drop them at the same time. Which one hits first?

 

The Apple

 

Bautista hits the ground first.

 

Wins the internet for today

Actually it's Bautista with the Apple

 

Google flying heli inside a moving truck. It's been done. The air in the enclosed cabin moves with it.

 

So out of date...

Bautista doesn't touch the ground.

He's laying on top of Sam Lowes...

 

I actually almost said Lowes.

But Bautista is a longer running joke.

 

If we're going with history, Xaus, no contest.
