thanks for the "invest in the best" lead. It has a trail of Koplin legacy, vision and future. Nice pictures of Sky Dragon in Germany at: http://tinyurl.com/39ocpz
According to the last photo,Sky/Air Dragon IV was first flown in Germany in 2003. This appears to be the same prototype that was then flown by Sanswire and shown on San Diego TV news in 2006.
Agree Air Dragon has been conceived as a High Altitude Airship (HAA)and high altitude testing is linked to the development of this type of semi-rigid airship.
