NEW!
Fire in the engines!
Alt + PgUp-PgDn/Auxiliary (without Alt): Fire in engine one.
B/Beacon: Fire in engine two.
L/Headlights: Fire in engine three.
K/Hazard light: Fire in engine four.
I can't stop the engines since the plane won't fly with lopsided engines but you get a lot of smoke and some flames (as in orange smoke) for RP purposes.

Fixed suspension which hopefully leads to less "spinning on the ground" behaviour.

Fixed a loose gauge in cockpit and cockpit windows.
