How short are these short flights? The hugely popular Ponte Aérea (https://en.wikipedia.org/wiki/Ponte_A%C3%A9rea https://en.wikipedia.org/wiki/Ponte_A%C3%A9rea) has a flight duration of one hour.
- robonerd 4y agoThat flight is about 230 miles (365 km) as the crow flies, and they're doing it with 737s that seat 100+ each and fly dozens of these flights a day. Compare that to this battery plane that can fly 200 miles: https://cleantechnica.com/2020/01/29/rolls-royce-claims-its-latest-electric-airplane-battery-has-the-highest-energy-density/ https://cleantechnica.com/2020/01/29/rolls-royce-claims-its-... These aren't in the same ballpark; they aren't even playing the same game. If you want something to replace that plane route, I suggest buying a lot of buses.
