I can't imagine the human body can withstand that type of force
The X-15 served it's purpose. But it wasn't an air-breather like the Waverider.
One of my first jobs was as USAF junior engineer on the XLR-99 rocket motor from Reaction Motors. It was retired shortly after that.

Was that the big motor, or the one they flew with on the initial flights? Not that either of them were slouches, just curious
Replaced the XLR-11(?) cluster IIRC. The XLR-99 was a single motor and could be throttled.

I remember the first flight.Every kid had a model of the X-15 in their room.
