A massive exaggeration. The only explosion was the engine nozzles making contact with cold sea water, which won’t happen on land. Two hours later the vast majority of the booster is still; afloat.
Decisionnto go for a water landing seems based on the tower in top of the launch tower having been knocked askew and nothing to do with the booster - a simple fix which shouldn’t delay the next launch.
Starship - stripped of heat tiles and given an aggressive re-entry profile it wasn’t expected to survive….. performed perfectly.
Future launches will use the Starship Mk2 with increased fuel and redesigned flaps. Future Boosters increase thrust/payload by 50% with Raptor 3s.
