Jet engine powered by Branson's hot air
At the beginning of the month a giant A380 Airbus made the first ever flight by a commercial aircraft with one of its four engines powered by synthetic fuel (which can be made from a range of hydrocarbon source material including natural gas or organic plant matter).
I wrote about it, and I expect others did, but I don't remember seeing any other reports.
Yesterday a Virgin jet did the same thing and it made headline news on TV, radio and in all the papers.
There are subtle differences between the two flights but I would suggest the major difference is that one of them was powered by Sir Richard Branson's formidable PR charisma.
