How fast will future planes go?

The aircraft in question is called the 'Overture' and it's being made by Boom Supersonic, an American aviation company. Overtures are promising to be the world's fastest airliner and reach speeds of Mach 1.7 (over 1,300 miles per hour), which is over double the speed of current airliners.



The future of aviation is currently splitting into two high-speed paths: Supersonic and Hypersonic travel. Several companies, most notably Boom Supersonic with its "Overture" jet, are working to return supersonic flight to the masses by 2030, with target speeds of Mach 1.7 (about 1,300 mph). This would cut a flight from New York to London down to roughly 3.5 hours. Looking further ahead into the mid-2030s and 2040s, researchers are exploring hypersonic flight, which exceeds Mach 5 (over 3,800 mph). At these speeds, aircraft would travel through the upper atmosphere, allowing for "anywhere to anywhere" travel in under two hours. However, the speed of future "standard" commercial flight is actually trending toward being slower or remaining constant as airlines prioritize fuel efficiency and sustainability over raw velocity. The next generation of narrow-body jets will likely maintain current speeds of 500–600 mph but utilize "Open Fan" engine technology or hydrogen propulsion to reach net-zero emissions, proving that in 2026, "green" is often the new "fast."

Low prices and an ever-expanding route network make it possible: 9 billion passengers are expected in the air by 2050. Thus, the passenger volume in aviation of the future will more than double compared to the current level.

NASA says supersonic passenger aircraft could get you from NYC to London in less than 2 hours. NASA is exploring the idea of a passenger jet that could theoretically fly from New York City to London up to four times faster than today's airliners.

According to Drela, today's airplane builders actually favor a smaller, lighter, and therefore slower aircraft that peaks its fuel efficiency at slower speeds. (Cars also become more efficient at slower speeds on highways.)

The wings of a 747 are nowhere near strong enough to mount an engine capable of supersonic flight. Generally, engines used in aircraft like the Concorde or the F-22 are skinny and long. They also weigh quite a fair amount, further requiring a complete overhaul of the way the engines would be supported.

Lifespan. Humans will almost certainly evolve to live longer—much longer. Life cycles evolve in response to mortality rates, how likely predators and other threats are to kill you. When mortality rates are high, animals must reproduce young, or might not reproduce at all.
