The Insane Math Behind a 20-Hour Non-Stop Flight

You're about to fly 15,000 kilometers non-stop from Singapore to New York — but when you board, half the cabin is missing. No economy class. No cargo hold. Just 161 passengers in a jet built for 300. That's not poor ticket sales — it's the Breguet Range Equation in action, and it's so unforgiving it killed the last plane that tried this route. The fuel doesn't just power the flight; it fights it, burning itself just to carry itself, compounding with every kilometer until the math forces a choice: carry people, or reach the destination.
