The bullet is already travelling at the speed of the aircraft before it's fired but it would still travel from the gun at the muzzle velocity of the gun and theoretically would only appear stationary for the micro second that it left the barrel. If you travel on a train doing 125mph and then jump into the air you land in exactly the same spot because you are also travelling at 125mph along with the air and everything else in the carriage so when you jump you don't get hit by the back of the carriage. If you did the same experiment standing on the roof of the train ( assuming you could keep your balance etc ) you would not land in the same spot because although you are travelling at 125 mph, the surrounding air is not and would create a resistance that would slow you down.

If the plane and the bullet were travelling at exactly the same speed, yes. But gravity would still have an effect, so the bullet would fall to earth.

Yes. By relative velocity it would be stationary to anyone observing from the ground. From an observer on the plane it would be leaving backwards at the speed the bullet was fired.

Depends on the mass of the bullet and it's aerodynamic characteristics. In theory yes. But in reality it would just be travelling in totally the opposite direction at a velocity relative to the force that was used to propel it. If this were not the case, then how come WWII aircraft had tail guns. Maybe the Germans just flew around our stationary bullets!!
A similar one is, if an aeroplane is about to crash, why don't you wait until it is 1 metre of the ground, then just step out. Surely a 1m fall would not kill you? I think it would in this instance, your terminal velocity would be exactly the same as the falling aircraft.

The bullet would hit the ground as if it had been dropped. The same distance would be traveled by the bullet but the velocity would cause either point to be reached at the same instant assuming the bullet to be traveling on a level plane. james h

The same philosophy would be applied if the bullet was fired foward from the plane, the bullets speed would be increased by the planes speed.

Yes
A plane chasing from behind would then crash into the bullet with "the speed of a bullet"

Stationary for a moment yes. Then gravity would call it home.

Correct only for a moment and then gravity drags it to earth

you are absolutely right !
You have to add up the two speeds, but since they are in the opposite direction one of them has a negative sign, so the sum of the two is zero.
