A solar-powered plane completed its three-day flight across the Pacific Ocean without fuel Saturday.
The Solar Impulse 2 took off from Hawaii on Thursday and touched down in San Francisco just before midnight.
The flight was a demonstration for the solar-powered plane, which is said to weigh as little as an SUV.
