@mcrs987 Could it have been related to the propellant leak? Pressurised the nose and meant the forces acting on the payload door which the actuators couldn’t fight?
Falcon 9 launched 21 @Starlink satellites to orbit overnight. After stage separation, the first stage booster returned to Earth and landed on the Just Read the Instructions droneship, which was stationed in the Atlantic Ocean ~250 nautical miles off the coast of Florida.
Following the successful landing, an off-nominal fire in the aft end of the rocket damaged one of the booster's landing legs which resulted in it tipping over.
While disappointing to lose a rocket after a successful mission, the team will use the data to make Falcon even more reliable on ascent and landing.
@GunsAndRockets1@Truthful_ast Propellant cross feed was originally planned for falcon heavy but due to its complexity and the amount of work being done to reinforce the centre core, this was dropped.
