A simple question from a simple mind:
When they do a full burn, especially the booster and all 33 of its Raptor 3 engines - how do they hold the craft down?
One assumes it has 'holding clamps', but 33 engines going full blast. Doesn't the whole thing (with starship), weigh 5000tons, so the engines have to - at least - be able to move 5000tons. So the holding clamps can handle 5001 tons...?
