That was awe inspiring.
Not only that both the booster and Starship made it back to successful water landings - but the manner it was done.
Once the front of the flap had a burn through and the rear started to come apart and melt so the internal structure could be seen it was obvious no one, not even the SpaceX commentators, expected it t9 last more than a few seconds before disintegrating.
That it managed not only hold together but continue to function up and including performing the final pitch up manoeuvre before the landing touch down burn was mind blowing and an sign of the strength of the structure - and stainless steel.
That Starlink also gave continuous coverage all the way down was also amazing - in contrast to the Boeing Starliner which has no video downlink capability.
I don’t imagine reinforcing the tiles on the flap will be much of an issue. All looks good for IFT-5 as none of the launch licence red lines were breached.
More important, from NASA’s point of view, that was the fourth successful booster launch so well on the way to being able to launch the lunar lander and supporting tankers where re-entry isn’t a factor.
