Boeing’s Exit From Space Plane Project Is A Lesson In Why We Need To Kill Zombies
Sometimes you just have to kill the zombie.
We learned Wednesday that Boeing has abruptly decided to end its participation in the Defense Advanced Research Projects Agency’s Experimental Space Plane (XSP) program – an effort intended to build and fly a reusable rocket “ten times in ten days.” Admittedly, it’s a bit personal for me, since XSP comprised a significant portion of my space portfolio during my most recent stint at DARPA.
I was not familiar with this project, and was a bit surprised that Boeing had participated in a space plane project other than X-37.
