the bullet? Let's say the bullet is traveling at 4000 kmph, will the bullet be slower inside the plane? or if ever the bullet and the plane is traveling at the same speed, will the bullet, shot in same direction as the plane, be hovering inside the plane? Or let's say the bullet maybe faster, if then what will happen if you fire it side ways, or at the opposite direction of the plane? since your moving almost at the same speed as the bullet, and you fire at the rear, will the bullet stop and drop?
If you fire it side ways while in the plane traveling at the same speed as the bullet will the trajectory change direction?
So if you fire the bullet at the rear it will be 4000kmph - 4000 so the bullet's speed is 0? since if you fire it in front you will get 4000 + 4000 speed = 8000? am i right?
 
Your relative speed in same direction is (4000 - 3500) = 500 kmph = 500*1000/3600=138.9 m/s.
the bullet will definitely slow down, due to air resistance but the bullet will also bend towards ground due to gravity.and it will have fall to ground before your plane covers the distance.in other directions no risk.
 
The bullet is moving at the same velocity as the plane prior to being fired. No matter what direction you fire the bullet, it is traveling at the same velocity as the plane when it leaves the gun.

Velocity implies direction, so the ground speed will vary depending on the direction, but the bullet, the gun, the person firing the gun and the plane are are traveling at the same velocity.

To give you an idea, the earth rotates at about 1000 mph. If you jump in the air for 1/2 a second, does the earth spin 0.14 miles underneath you? Of course not. It is cause you are spinning with the earth at the same speed.
 
The bullet will move at '3500 kmph' relative to you whichever direction you fire it, until it tears a hole in the cabin, causing the plane and yourself to disintegrate.
