Person on the airplane: Crate will appear to be dropping straight down. Person on the ground: Crate will be curving in the direction the plane is moving.

Both hit at the same time.
yes because they have the same gravitational potential
No. That's why a bullet shot horizontally from a gun and a bullet dropped from the muzzle of the gun at the same time both hit the ground at the same time.
at what q from the horizontal should be threw a rock so that it has greatest range
Please describe how you drop something 'horizontally'
somebody dropped a piece of cheese..
If the person outside the plane managed to move along with the plane, at 400 mph, the ball would appear to fall vertically. At lower speeds, the plane and ball would be in sight for a short period of time and the ball would appear to move horizontally with the plane.
It was named the Enola Gay.

It was a B-29 airplane which dropped the atomic bomb over Nagasaki.
it is still hot but lying on the ground! :D
It doesn't matter whether the object is thrown down, up, horizontally, or diagonally. Once it leaves the thrower's hand, it is accelerated downward by an amount equal to acceleration of gravity on the planet where this is all happening. On Earth, if you throw an object horizontally, it accelerates downward at the rate of 9.8 meters per second2 ... just as it would if you simply dropped it. Whether it's dropped or thrown horizontally, it hits the ground at the same time.
the Enola Gay
No. The horizontal distance depends on how close the the ground the gun is. From the firing position, a bullet dropped to the ground will strike the ground in the same time as a bullet shot horizontally forward.

No. Acceleration due to gravity is constant. That's why a hollow lead ball dropped from a height will strike at the same time as solid lead ball of equal dimensions. Whats important is the shape of the glider and the air resistance that it can generate. In a vacuum both would fall at an equal rate.
