testing, trials and research are not fails...its just part of the process...
but when you announce success and then demonstrate your product and it fails, then that's a fail!...hello!...
did you see elon musk present his new version of a pick up truck announcing that it had shatter proof windows?....a shotput was thrown at the window and it shattered...the shot put was throw at other windows and they all shattered...
THATS A FAILURE...
he may later fix the problem....but the first announcement of success and demonstration was in fact a FAILURE...
A) B.S. crazy B) stoned to bejesus half the day C) being propped up by hundreds of millions of federal tax dollars (technically that's for his crappy cars, about which, of course, there is very little that is "green.")
On that note, I would encourage anyone interested to search "Elon Musk fraud" or similar. Pretty interesting results.
