Elon Musk recently tweeted that they would be reworking the next flight vehicles so the ship could fire its engines while it was still attached to the booster. Before we watch the next Starship launch live, let's break this down with a proper engineering analysis to see why SpaceX is making the switch. Will this end in disaster? Let's find out!
