So, I've lived within earshot of the Cape since 1985, and I'm pretty used to hearing launches. Tonight, I had a new experience. I was working on a signal distortion problem with a colleague when I heard the rumble of the launch. "Rocket just launched", I said. He was on Google chat with me and said, "It did?". He lives a few miles south of me and so he gets the sound waves a few seconds later ;). A couple of minutes later I did a double-take. "THAT's a new sound!". I've heard rockets blow before, but I've never heard one come back to land. Then I checked the internet to confirm what my ears had already told me. Congrats to SpaceX and thank you for not landing it on my house!
