OK, this is more of an avionics than astronomy news, but: Aerion just got their first order for 20 planes, $120 million each.

I'm not sure if this should go into the astronomy "News" category but it is interesting.

It's a working through of the question: "How long would it take to turn a planets mass into a Dyson Shell/Sphere?"
