John Woodfield RC Gliders

An evening pause: Seems appropriate with Ingenuity flying about on Mars. From the youtube webpage:

This was the maiden flight of my latest design. It was a bit of a mash-up, using existing wings and tail from old models. It weighs 1.5kg and was flying in about 7-10mph of wind. I feel it will be happier in about 5mph. The all-moving tail needs changing slightly as it developed some serious flutter if I picked up too much airspeed.

Hat tip Cotour.

A glider sets new altitude record

The Perlan-2 glider yesterday set a new altitude record, reaching an altitude of more than fourteen miles.

Then on September 2, Perlan pilots Jim Payne and Tim Gardner strapped themselves in and rode the glider to an altitude of 76,000 ft (23,000 m), setting a new flight record. This is higher than Lockheed Martin’s jet-powered U2 spy plane flown by the CIA, which reached 73,700 ft (22,475 m), and places it amongst a handful of manned aircraft to sustain flight at such as altitude.

Implied but unstated in the article at the link is the military value of this technology, once combined with drone technology.
