Watch this carefully. Youíll see the six radial lobes of the plume then about 6 seconds later two new, darker gray lobes going vertically near the center. That timing correlates to the release of debris chunks in other videos, so I think thatís the moment the pad broke apart.

In this episode I travel to Tephaujes beach with Charles and Star searching for heat tiles from Starship 24. We found more than heat tiles. We found a COPV tank that had survived the explosion ,falling 20 miles and floating 200 miles before the surf pushed it up on the beach. This tank is 12' long and weighs about 400 pounds.

Crosspost of an excellent deep dive video (part 1) that, among other things, covers B7 upgrades and analysis of B7 failures during IFT-1.

Thereís also this comment on the video:

New Fire Suppression System Dramatically Increases Superheavy's Performance!

While the 2nd Integrated Test Flight of Starship ultimately ended in the loss of both vehicles, it was undoubtably a massive improvement from SpaceX's first attempt.

This episode is a deep dive analysis of critical upgrades to Starship Superheavy.

Disclaimer: There is a very large focus placed on Booster 7 in this episode. There were a lot of lessons learned from IFT-1 and its important to understand why each of the changes to Booster 9 were necessary.

Hopefully this will help make sense out of a lot of the items listed in the 63 Corrective Actions from the FAA shared by @elonmusk a few months ago.

If you enjoy this then please share it!
