>>12790177So you just have no idea what you're talking about then.
SN10 came in too hard and they throttled up to prevent a RUD, but Raptor's TWR is insanely off the charts for a nearly empty vehicle (~1.5x).
So it basically hit the ground and bounced up like 5 meters; so they cut the engines and it dropped again.
The vibration, coupled with a potentially failed leg (it was leaning), probably meant that something got dislodged or some internal part failed. This led to a containment loss, so fuel flowed downwards from the tank (whatever was left) and made contact with the very hot engines.
The heat transferred and ignited the methalOx.
If you follow the explosion sequence, the explosion starts in the top of the set of rings above where the engines are and moves downwards. Enough fuel eventually ignites in the explosion, that the wave front tears apart the bottom section and takes the 3 engines with it. Most of the initial explosion is ridirected back into the engine skirt and that disassembles rapidly while simultaneously launching the rest of the vehicle straight
up.So for SN11 to SN15, they will likely have to significantly reinforce the landing skirt and engines. Also will have to investigate maybe firing 2 raptors down to landing, but throttling them lower instead of having 1 raptor and throttled lower.
In case your monkey brain doesn't understand
>Landing impact: major vibration event>bounce: gain potential energy>engine cut off: convert potential to kinetic energy>bounce impact (permanent): major vibration event
