I read the following today:
"Gilmour has previously pointed out that it took Elon Musk four attempts to launch the Falcon 9 rocket successfully, and Musk is now experiencing a similar sequence of unsuccessful initial Starship launches"
Interestingly, the Von Braun rocket team had no significant failures with the Saturn V program over a half century ago....in fact their record at NASA was almost faultless.
The take-away may be Gilmour and Musk are clearly not "Rocket Scientists"
P.S.
I admit to setting my Mum's hedge on fire with my home built zinc-dust and sulphur powered rocket in the 1970's. It looked pretty cool until it arced into
the hedge.
