“Good Morning Abu Dhabi! Assalamu Alaikkum!” Bertrand Piccard, one of the Swiss pilots who flew for 48 hours as part of the last leg of the flight from Cairo, greeted the crowd of Emirati officials and journalists as he stepped out of the cockpit in an orange jacket and embraced co-pilot Andre Borschberg. “Sultan Al Jaber, we are back. We had promised we will be back,” Piccard called upon the Chairman of Masdar, the official sponsor and host of Solar Impulse 2. It was a moment Piccard, 58, and Borschberg, 63, had waited for the last 17 years. Tears and emotions flowed freely as the pilots relived their experiences.
