If New Glenn ever launched people they’d build the escape system into the crew module, much as SpaceX does with Crew Dragon.
replyMaybe; SpaceX isn't taking that approach for Starship thus far.
replyStarship itself could potentially hot launch from the booster in the ground to get away. Hopefully the latching system is controlled by the Starship side.
replyIt almost definitely cannot. It already has a far lower thrust-to-weight ratio than real launch escape systems (1.x at best versus 6-10+)[1][2], and it would only be able to light its three sea-level engines since the vacuum-optimized engines would be unstable and likely rip themselves apart at 1 ATM.*
reply*correction: Vac raptors can run at sea level in a test stand. Still doubtful that its safe/reliable and in either case it would still be far too slow.
