Blimp (airship) Script

I am attempting to write a Javascript that would control the flight of an airship.

I would like: to use arrow keys to control the pitch and yaw of an airship. move the ship forward in the direction of the Z of the ship (not the world). the rudder controls to Zero out once the key is released. the speed of the ship (low, med, high) governed by number keys 1,2,3.

Please point me to any tutorials you can think of that might assist me. Many thanks!
