The NASA manager overseeing development of Boeing and SpaceX's commercial crew ferry ships says the space agency has approved SpaceX's proposal to strap in astronauts atop Falcon 9 rockets, then fuel the launchers in the final hour of the countdown as the company does for its uncrewed missions.
The "load-and-go" procedure has become standard for SpaceX's satellite launches, in which an automatic countdown sequencer commands chilled kerosene and cryogenic liquid oxygen to flow into the Falcon 9 rocket in the final minutes before liftoff.
[...] SpaceX's "load-and-go" procedure raised concerns after a Falcon 9 rocket exploded on its launch pad at Cape Canaveral in September 2016. The fiery accident occurred in the final minutes of a countdown while propellants were flowing into the rocket before a hold-down engine firing, destroying the launcher and an Israeli-owned communications satellite on-board.
Officials from SpaceX said the Crew Dragon's escape system, comprising a set of high-thrust SuperDraco engines around the circumference of the capsule, would be quick enough to push the spacecraft and its crew away from such an explosion during fueling.
The abort thrusters will be activated and armed before fueling of the Falcon 9 during crewed launches.
SpaceX plans an unmanned, in-flight abort test prior to the first crewed flight, which is tentatively scheduled for April 2019.

Usually people are hunting devils within themselves, but finding them in others.
Anyway, calling somebody pedo as a revenge for being called an idiot tells a lot about the person; especially given our current environment and their relative standing. Mask is a total ass and he can have his rocket where his submarine already is.

Sounds like a view that is entirely anecdotal and rooted in media sensationalism. There's no juicier story than a Republican gay-bashing politician found to have a gay lover. Or the Atkins diet guy fattening up, having a history of heart failure, and dying from falling down on the street. Rather than pedophilia, Musk is guilty of perpetuating a stereotype of Thailand, although not an entirely unfounded one [wikipedia.org].
He is allowed to defend himself on social media, even given his "relative standing". But facts aside, as long as Musk gives us BFR, he could shoot a guy in the middle of Bel Air and I wouldn't care. Your disdain is worthless and beneath the Gaze of the Musky One.

So all these critics of Musk are crypto-rocketmen with that secret lust for the cryogenically-fueled shaft? Ye gods! The internet has fallen further than I could possibly imagine!
