Watching the raw video stream today, I couldn't help but feel that we're looking at a quantum leap in rocket technology. The intensity of sound and exhaust from the engines was something I have never seen from a rocket that size before. I'm curious how the specific impulse of the newest Merlin compares to what ULA is using, considering a lot of their stuff is either Russian made or designs from the 60's. It's possible they will not only capture the launch market, but the engine market for other manufacturers as well.
