I had a mun lander with engines mounted x6 symmetry on the sides. the new weaker collapsible landing legs knocked off 1 of the 6 engines on landing, making true straight flight impossible. so i took off about 5 feet, rotated to the opposite engine, and knocked it off on the terrain to regain symmetry. as soon as i saw it popped off, i stomped the throttle and burned back in to kerbin orbit on my 4 remaining engines, rerouted fuel to the good engines for a retroburn, then a safe landing home.
