But then they would've been using many smaller ICE or jet engines already to get redundancy. I suspect the reason is that it's easier to get that kind of redundancy with electric motors - they're more compact, lighter weight, less overhead for each.
- jasonwatkinspdx 4y agoWe do. It wasn't until the 80s that twin engine airliners were certified for long flights. Before then it was 3 or 4 engine only. It took a lot of effort to get jet engines that reliable too. Single vs dual engine helicopter is a big safety distinction. There's heavy lift and military helicopters with 3 engines.
