A camel calf is seen among a herd in the desert near Dakhla in Morocco-administered Western Sahara, on October 13, 2019. In the Oued Eddahab desert in Western Sahara, Habiboullah Dlimi raises dairy and racing camels just like his ancestors used to, but with a little help from modern technology. While his animals roam free and are milked traditionally, by hand, at dawn and dusk, they are watched over by hired herders and Dlimi follows GPS coordinates across the desert in a 4X4 vehicle to reach them.

“NASA's Pathfinder, Pathfinder Plus, Centurion and Helios Prototype were an evolutionary series of solar- and fuel-cell-system-powered unmanned aerial vehicles. AeroVironment, Inc. developed the vehicles under NASA's Environmental Research Aircraft and Sensor Technology (ERAST) program. They were built to develop the technologies that would allow long-term, high-altitude aircraft to serve as “atmospheric satellites”, to perform atmospheric research tasks as well as serve as communications platforms”. – Wikipedia

The 18-hour flight was a functional checkout of the aircraft's systems and performance in preparation for an attempt to reach sustained flight at 100,000 feet altitude later in the summer.

Burnouts became a serious form of competition and entertainment in their own right. Considerable prize money or goods are sometimes involved, and cars may even be sponsored or purpose-built specifically as “burnout cars”. Burnout contests are judged on crowd response, with style and attitude therefore being important factors. Such contests are particularly popular in Australia but often occur in North America as well.
