As dawn breaks over Silicon Valley, the world is getting its first look at Pathfinder 1, a prototype electric airship that its maker LTA Research hopes
It’s even more entertaining: it’s airspeed not ground speed, so the trip duration depends on the direction and force of the wind at the heigh it travels in (and that’s a lot worse for airships that aircraft because the formar have a much larger area facing the wind than the latter).
So that trip at top speed would likelly be shorter than that on the way to London, but longer than that on the way back (as the predominant winds - except during the El Niño - are from the west).
