Solar Impulse 2 Arrives at Moffett Field
April 23, 2016
CAFE Field Trip – by John Palmerlee
CAFE received an invitation to the Solar Impulse 2 landing at Moffett field, and we decided to make it a field trip to support the effort and watch the landing slated for midnight on Saturday. The airplane was about to complete a three day non-stop flight from Hawaii on solar power alone.
Bruno Mombrinie and I (CAFE Board) and our EAS 2016 Coordinator Yolanka Wulff, left for the Marin Headlands at about 15:30 Saturday. Our plan was to get to the west end of the headlands road so we could see Solar Impulse when it first arrived sometime after 17:00.
There was moderate traffic at the headlands, making us think everyone had turned out to see the arrival. What else would anyone be thinking of today, anyway? Not. In the three hours we were there, only a handful of people knew about the event, so we shared the story with many.
Finding a parking spot was a stroke of luck, right on one of the last headland ridges with a great view of the Golden Gate and the entire Bay Area. Visibility must have been near 100 miles. We were high enough to be well above the bridge towers, and couldn’t decide whether Solar Impulse would be above or below us when it passed. Turns out it was well above us at about 4,000 feet.
We first saw it over the ridge to the west - a long bent stick below the high clouds. Bertrand Piccard had flown for over 55 hours from Hawaii, but had another 7 to go before he would land. That’s a long time to wait for winds to calm at your destination. A black dot nearby was a helicopter flown by the other Solar Impulse pilot André Borschberg, darting about the big plane as if it were a sparrow with a condor. Through the camera lens, I could watch the four propellers spinning - big, slow, efficient, two bladed props.
The purpose of this phase of the flight was to say a long “Hello” to the Bay Area, get some video footage of the plane over landmarks, and to wait for landing once the wind settled down. To us, it was all a treat. Bruno brought a long strip of black fabric and white duct tape, which we turned into a sign on the chance that Bertrand looked our way. The sign said “BIENVENUE BERTRAND” which means "Welcome Bertrand" in French (picture below). Solar Impulse passed over us many times, but we never learned if he actually saw the sign. There was a lot to look at from 4,000 feet, and he was dealing with constant direction from the MCC (Monaco Mission Control Center) and commands from local ATC; so it wasn’t just sightseeing for him. Keep in mind he’d had less than 3 hours worth of 20 minute naps over the last 3 days. One must somehow stay alert on a flight almost twice the duration of Lindbergh’s Atlantic crossing.
At 20:00 we had to leave for check-in at the NASA Ames barracks. The campus is large, with many buildings in disrepair and a background of flight history everywhere: the blimp hangar skeleton under major repair, a NASA U-2 sitting on a ramp behind other unused aircraft.
The ramp security checked our names off a list and turned us loose with a group of a few hundred people consisting of Solar Impulse team members and the invited guests from public and government sectors.
Tesla was present as a sponsor, and provided Model S vehicles for the two pilots, Bertrand and André, for their week stay in SF. On Sunday (4-24) Bruce Nyden, the local Electric Auto Association president and Model S owner (yeah, the “other” EAA), said he came across a French speaking group in a new blue Model S P90D with factory plates near a local Bodega Bay chowder house. By his description, it appears that the driver was Bertrand Piccard - he was sitting with the driver’s door open while fussing with the navigation system (yes, he’s done his share of navigating :-). Bruce spoke with a woman getting out of the back seat and noted another woman in back met the description of Michelle, Bertrand’s wife. Nice coincidence - interesting how electric vehicles attract electric vehicles.
The Solar impulse landing at Moffett was quite serene, except for a jet helicopter running up during the entire approach. I wished it wasn’t there. Despite that, I got a video of the landing with my camera - looked like a UFO on approach with a full span array of landing lights (236 feet of them). There were 20 team members on the runway to grab the bird once it slowed from the landing, who then moved it under 'people power' off the runway to the waiting crowd. The main and tail wheels pivot completely so it can be towed sideways if needed, particularly for rolling into its inflatable hangar.
After taking several minutes to regain his land legs, Bertrand spoke to the group. He said what a privilege it is to participate in this adventure, and how he hopes it will help everyone become explorers - to free themselves from the old ways of thinking and fear of the future. He hopes one day everyone can have an experience like this that changes the way they live. The following is an excerpt from his speech:
"…we would like other people to understand, that everybody can do the same, everybody can (thrive in) a world with clean technologies that protect the environment, that brings social peace, wealth to all the population. That if we want to fight poverty we have to give access to renewable energies."
Piccard invited everyone to “Go for it!” as explorers… to experience life as life is made for.

Historic CAFE 400 Video Released
April 15, 2014
In advance of the CAFE Electric Aircraft Symposium we are proud to share an historic video from the CAFE Archive. This 47 minute video shows CAFE's first tech prizes – The CAFE 400 races, which were conducted from 1981 to 1990 at the Santa Rosa Air Center.
These 400 mile flight competitions were scored according to the CAFE Formula of Speed x MPG x Payload and attracted most of the famous aircraft designers from the world of EAA. It is amazing to see how many of their innovations were incorporated into GA aircraft of today. Nearly 50 aircraft competed including Roy LoPresti's factory team from Mooney, Burt and Dick Rutan, Mike Melvill, Tom Hamilton, Gene Sheehan and the perennial winner, Gary Hertzler. The event demanded astute navigation and power management in addition to fastidious preparation of engine and airframe. In the 10 years of CAFE 400 racing, there was never an injury or serious accident."

Astounding Final Results from the Green Flight Challenge Sponsored by Google
The 2011 Green Flight Challenge sponsored by Google marks an historic achievement in aviation—the first demonstration of practical, cross-country emission-free flight. Team Pipistrel-USA.com’s winning 4 seat, electric-powered aircraft, the Taurus G4, flew nearly 200 miles non-stop while achieving 403.5 passenger MPG! Its astounding efficiency was more than twice that of the piston-powered aircraft in the competition. Equally promising: Team e-Genius won the Lindbergh Prize for Quietest Aircraft, with a peak take off noise of just 59.5 dBA at a 250 foot sideline. This achievement heralds the real transformative potential unique to electric powered aircraft—the capability to be quiet enough to land very near dwellings and businesses.
Years from now, these first Green Flight Challenge team members will be recognized as the pioneers of the Age of Electric Flight. CAFE is already discussing plans for GFC II and will publish more on that here soon.
Thanks to Everyone Who Made the Green Flight Challenge Happen!
The CAFE Foundation wishes to thank all of their sponsors, partners and volunteers for making this historic competition happen. Together we have achieved something great and the future for Green Flight looks bright!
