But recent depictions (attached) seem to show the same problem. Furthermore, the aft pointing nozzles seem beefier than the others. So what's going on?

I believe those thrusters are only used to de-orbit the vehicle, once the cargo module has been jettisoned. The lightweight cargo module will decay naturally and presumably completely burn up in the atmosphere.

 "Only runway landing space vehicle in existence"

  Who's going to break the news to the X-34?

I wonder how the runway landings are actually going to work out once (if?) this thing starts flying. One of their selling points is "able to land at any runway able to handle large planes", but surely that would need the airport to at least partially shut down to process it and I don't think any big airports would want to do that. Landing at Air Force bases seems much more reasonable, and it's not like there's a big lack of those.

Sure would be cool to see it come screaming down the runway while you're waiting for your flight though!

The two "in existence" are not available. Would Boeing build another for commercial use - on non-USA missions? Is it allowed to - isn't it secret tec? And doesn't it use Hypergolics... so more dangerous at landing, unlike DC.

Boeing has repeatedly proposed derivatives of X-37 for NASA or commercial use. ISS crew and cargo, freeflying labs, satellite servicing/recovery, etc. And their processing facility has room for like 6 X-37Bs.

Nice paper, interesting mission. Dang, the U.N entering the space race, sounds a bit like Star Trek...

UN has had a space exploration office since i think the late 1960's but it's never really done anything of note.
