Thanks, imawswami. Question:

symphyl [in post #17248] gave the link

[very informative: thanks]

In the second paragraph above the pictures, in the paragraph beginning "As we designed the concept...", it says:

"These vehicles will use a variety of schemes for propulsion, including conventional propellers and unconventional buoyancy-modification schemes that allow vehicles to propel themselves by porpoising through the air at about 30 to 50 knots, enabling them to overcome all but the most unusual near-space winds."

Could this be a reference to the Sky Worm/Sky Dragon concept?
I had the idea from the Sky Dragon video
http://www.exn.ca/news/video/exn2005/11/28/exn20051128-balloon.asx
that the motion of Sky Dragon was more passive, but the motors on each of the forward segments could possibly allow "porpoising".

Thanks.
