Sorry, but you're wrong. There are no accelerative forces on the hummingbird except that of gravity, and its own acceleration up (to hover). There are no lateral accelerative forces on it whatsoever. You're an engineer, I would figure you'd have learned about relativity by now...it's a basic theory in physics.
The bird doesn't get knocked back, it's just not moving laterally...but the bus is.

Inertial frames of reference, which say that an object can only accelerate in a direction if a physical force is applied. Basic physics. But no force is transformed through the air to hummingbird. The bus is accelerating because of the tires, but the air inside of the bus isn't, assuming there aren't any crazy variables like the vents being open or windows being opened. The air doesn't move and the bird doesn't move because of this.
Ever tried to toss something up in the air when a jet is taking off? It doesn't go shooting towards the back.

h:No. The bird is not attached to the car, the ball is.

The object would only move as far back as the amount of time you gave it (by using the height thrown as that variable) and by how much faster the plane was moving since the time the object was thrown. However... Planes are pressurized (not sure if that has any effect).

I don't believe that pressurization matters. It's just that planes don't accelerate very fast. And when you throw the ball, it has the same forward velocity as you at the time of release and since planes don't accelerate quickly, the ball has already fallen back down before you really gained any velocity on the ball.

wow, this thread got stupid. yes the hummingbird will be struck by the back of the bus. the air moving forward might push the hummingbird forward a little bit, because it is hovering on that air, but not by a lot
sheesh.
sheesh.
