Perhaps, you haven't noticed but I'm using this accident to discuss our national space program. Virgin Galactic has a plane that goes to 62 miles/100km. While this is great, in the short-term, it doesn't help our space program.
Btw, you don't think they need to revisit safety to assure their customers that it's not a one way trip? Do they even have a second plane? There's not a chance that there will be a commercial flight carrying paying customers within the next 2 years. Branson was saying this year just a month ago.
Neither will Virgin Galactic.
"You don't need to go to Congress and request an additional $1.7 billion for another ship."
Neither does Richard Branson.
