Thruster

Enos became the first chimp to orbit the earth on November 29, 1961, aboard a Mercury Atlas rocket. Although the mission plan originally called for three orbits, due to a malfunctioning thruster and other technical difficulties, flight controllers were forced to terminate Enos' flight after two orbits. Enos landed in the recovery area and was picked up 75 minutes after splashdown. He was found to be in good overall condition.

Nevertheless osteopaths are coming to regard themselves not so much as thrusters, or even as repositioners, of bones, but as releasers of the patient's own recuperative forces.

The executive is a thruster with ideas to expand or improve the business and his superiors fail to react—for whatever reason—and do not give acceptable explanations.

His hi-spec gear suggests that he's a corporate high-flyer and he's definitely a bit of a thruster, very much in control, taking care of business.
