Tired of rockets collapsing when physics initializes, but it would be fine if physics didn't start with a jerk? Irritated launch clamps can twist your rocket apart when physics starts for no apparent reason?

Lessen the effects of physics glitches and get back to designing rockets to handle flight, not to handle the forces applied
