Key Takeaways:
- The solar-powered Solar Impulse 2 (Si2) successfully completed its second-longest overwater flight from Hawaii to California, marking its first landing on the U.S. mainland as part of its round-the-world journey.
- Si2 is an advanced aircraft powered by over 17,000 solar panels and four electric motors, enabling it to fly continuously day and night with a wingspan comparable to a Boeing 747.
- Designed for extreme endurance flights, the Si2 features a single-pilot cockpit equipped for long durations with an autopilot, napping facilities, and a lavatory, although it requires extensive ground support and presents unique flight control challenges.
