Sad to say, the thing about which I know the most is the one about which I can say nothing except point you to what is public domain. Here is the video which XCOR released after we got a 67 second burn out of our LOX/Kerosene engine. That was about the max we could go with the tankage we had for that test series. It is also the first dual reciprocating pump fed rocket engine ever fired. Can you say “reliable” and “low maintenance”? Stay tuned for further developments this summer.
Although I was on the test stand crew, I was not assigned to console duties in the test bunker that day. If you look closely in the background, you will see me with an idiotic grin developing as it becomes obvious we are going all the way with the burn. Had I not known I was on camera I would probably have given a rebel yell at shutdown.
Sometime in the next year four of those engines, in a non-teststand form, will give our pet astronaut a kick in the seat which will put a similar smile on his face.
