Four Forces

Four Forces lets pilots, or anyone else who might be interested, explore the "four forces" of flight - Weight, Lift, Drag and Thrust. You "fly" an aircraft (in two dimensions only), and the magnitude and direction of each force is shown on screen. You control the aircraft using intuitive "pitch and power" sliders.

This is work-in-progress so please try it out and with any bug reports, suggestions, comments etc. This is an updated version with improved graphics and flight model, but there's still a long way to go.
