Spike is competing with NASA and Virgin Airlines to develop a commercial supersonic jet capable of breaking the 767 mph sound barrier.

Last month NASA revealed that it had carried out breakthrough tests of its version of the supersonic jet.

Experts working on the £289million ($390million) project tested the latest prototype inside a massive wind tunnel at NASA’s Langley Research Center.

Now Spike have gone one step further by carrying out seven short flights to examine the design and flight controls of the jet.

Some interesting dimensions [for me]

With things slowly proceeding [building is possible in autumn/winter], I’d like to mention some of the rules of thumb I’m going by. At one stage I needed to know about personal spaces, heights etc.

After all, aren’t truckers about to be replaced by robots, and diesel by battery power? The sucker in this scenario, we add, is anyone who believed such futuristic forecasts in the first place.

Said Mr. Buffett this week on Bloomberg TV: “Who knows when driverless trucks are going to come along and what level of penetration they have?”

All right, your call on that. Try this one:… More here ...
