What's cooler than an all-electric plane that can fly at
supersonic speeds? One that can take off and land vertically.
"I wish somebody would do that," Musk said during
a video chat with entrepreneurs. "If somebody doesn't do that,
maybe at some point in the future, I will."
At supersonic speeds, an aircraft could go from London to
Shanghai in about seven and a half hours. That compares with more than 11 hours
for a nonstop commercial flight. An electric plane would have major
environmental benefits, and the ability to launch like a rocket would enable
airports to eliminate runways and be much smaller, Musk said.
