An ultra light plane can stay in flight up to 2400 km (the World Record) with out an engine using thermal lift. Can a huge kite like airship (not a blimp) be built to indefinitely sail in and out of the jet stream orbiting the Earth somewhat like the ship off Peter Pan? enter image description here

This is a possible route that could be taken on this day's jet stream chart shown below.

This question was merged with First to Sail the Jet Stream Around the World because it is an exact duplicate of that question.
