Aviation Needs a Scalable Path to Decarbonization
How will aviation decarbonize—battery, hydrogen, or something else?
The Incredible Capabilities of the Modern Airplane
The airplane has come a long way since the days of the Wright brothers. Its modern capabilities would have seemed like science fiction to the pioneers of the late 19th and early 20th centuries. The Wright Flyer, built and flown in 1903, could stay aloft for no more than a minute, covering barely a thousand feet—if a tailwind was generous. And their feat was made possible, in no small part, by the high energy density of the gasoline that powered it.
The longest non-stop flights today span over 15,000 kilometers (49,212,598 feet), lasting more than 18 hours—routes like Singapore to New York. Qantas plans to launch an even longer journey in 2026: a non-stop flight from Sydney to London, covering over 17,000 kilometers in 20 hours, making it the longest commercial flight in history.
Can you imagine? A plane carrying over 200 passengers, staying aloft for 20 hours without refueling? To the Wright brothers, such a feat would have been pure fantasy. Yet today, point-to-point air travel to virtually anywhere on the planet is a reality. And while this achievement owes much to the ingenuity of engineers, the sophistication of modern aircraft, and a century of efficiency gains, it has been made possible, in no small part, by the extraordinary energy density of jet fuel.
One must remember that an airplane’s amazing capabilities is not just in the distance it can cover in a single flight. A Zeppelin could rival that. What sets it apart is speed—the sheer ability to transport you from the familiarity of your city to the foreignness of another world in less time than a leisurely afternoon.
The Titanic carried passengers across the Atlantic in about a week—seven days, give or take. The fastest Zeppelin crossing, with a strong tailwind, took nearly two days, though it was often longer. By the 1980s and ’90s, the Concorde shattered those limits, making the same journey in under three and a half hours, while conventional jets still required seven or more.
Concorde represented the pinnacle of commercial aviation speed, flying at more than twice the speed of sound. At a cruising altitude of 60,000 feet, passengers could see the curvature of the Earth—experiencing flight in a way no other commercial aircraft had ever allowed.
While the Wright Flyer was a fragile wooden frame draped in fabric, barely lifting off the ground, Concorde was a supersonic marvel, a triumph of engineering. Its delta-wing design, afterburning turbojet engines, and heat-resistant materials enabled sustained supersonic travel—an achievement still unmatched in commercial aviation.
It’s almost surreal to think it first took flight in 1969. But placed alongside the other feats of that era, it seems less surprising. This was the decade of the Apollo missions, an age when humanity touched the Moon. Even the futuristic visions of "The Jetsons" belonged to the ’60s—a time when the impossible seemed within reach.
