birdbrain stole my piece :-)
Does any one else think that the Sonic Cruiser looks a little like the XB-70 or even the SR-71 for that matter. The tails and engine nacelles do look similar. It might make sense especially seeing Boeing does have a bit of history with joint developing civil and military aircraft. I also didnt even think of the tanker option, which would probably be the mose useful military use as i cant see the Sonic Cruiser being a great freight lifter. Also what about a replacement for the RC-135's and other slower survelliance/spy aircraft?? With its speed, almost like a pocket SR-71/U-2 and those tails look like they could be pretty stealthy, same with the engines.
