slide/glide either way its the wrong terminology

i prefer lateral/vertical (or more specifically up/down/left/right) thrust (you could probably also call it perpendicular thrust) in place of slide. and i call glide "normal physics"

glide is for all intents and purposes newtonian physics mode. it works based off ships mass and acceleration values. it might not be as precise as the meathod i used in my scripted flight model but its close enough to pass as realistic (albeit with exasperated mass and acceleration).
what id like to see in physics features is thruster simulation, like what you have in space combat. for simplicity you can add fields to the thruster effects for amount of force that thruster puts out. then based on the normal and position of the thruster, the ships center of gravity, and the ships moi and mass data, proper torque and angular momentum is calculated for and applied to the ship. the input for that thruster is based on the use for field, possibly multiplying by a scale field for sanity. another sanity check would probibly be an angular momentum cap, so you dont **** up your matrix math by lost floating point precision.
