Tesla's Roadster just flew. Why only for seconds?

On 15 October 2026, Tesla's new Roadster hung upside down at the top of a curled ramp, let go, flipped in mid-air on jets of compressed air and landed on its wheels. It also jumped a line of parked vehicles. No wings, no rotors. Just air. So how does a car fly, and why only for a few seconds? We take it apart: floor fans that pin the car down, carbon-wrapped air tanks, ten nozzles, and the physics that sets the limit. Newton's third law, an astronaut flying on nitrogen jets in 1984, how hard the jets must push to hold up about two tonnes, why the tanks only buy about 8 seconds, why squeezed air is a poor way to store energy, and why 0-60 mph in 0.81 s needs more than tyre grip. Then nine years of delays, an honest look at whether you could use it every day (refilling and the law), the safety question, and what Tesla still hasn't told us. All physics numbers here are our own rough sums from stated assumptions (Tesla has not published the car's weight), so read them as "about". Tesla's figures, like 0.81 s and the thrust, are Tesla's claims and have not been measured independently. The car in our diagrams is a generic drawing, not Tesla's design. Footage marked "Footage: Tesla" is from Tesla's own reveal stream and clips, used in short excerpts for analysis; other Tesla cars are stock videos and photos.
