haha it's funny you mention that. I was thinking to myself 1 min ago that technically it's not a failed launch but an aborted one. thanks for pointing it out!
Not just technically. That was a _very_ successful test of their launch abort system and engine diagnostics. And of their ground crew for diagnosing and fixing it so quickly :)
The amazing thing for me was when one of their earlier launches aborted and they refueled and launched the same day. That's just obscene turnaround time compared to anything else that can reach LEO.
Apparently they couldn't do it this time due to the narrowness of the launch window, not because they couldn't be ready again in a few hours.
