Shaky Drive OXP  ver. 0.0.2

  Date: April 12th, 2016
Author: Astrobe, based on "Bullet Drive" by Wildblood


Imperfections in thrusters and mass imbalances within the ship are normally
automatically corrected by the flight control software.
However, at very high speeds, those corrections are no longer effective. The
ship starts to "shake" and has a tendency to "steer" in a some direction, and
becomes harder to control securely.
For this reason, the flight control software automatically disengage the Torus
drive when it detects a significant mass nearby; a security commonly known as
a "mass lock".
