Departure of Solar Impulse

Having been to Moffett Field for the arrival of Solar Impulse and then made another visit to the hangar while they were there, I wasn’t going to miss the departure. This might not seem like a difficult decision to make but if I tell you I had been away in Southern California for the weekend and having driven back on Sunday and then finding out that departure was scheduled for 5am on Monday and we would be required to get there at 2am and I would need to be up at 1am, you can see why this was a bit tougher to do.

However, I was committed at this point (or should have been) so I slept in the spare room so as to not disturb Nancy. Off for an early run. Traffic was no problem at that time as your might imagine. Once there it was back to the same issues as we had faced with the arrival. It was very dark. Hayman did the stills and I went for video but got some stills as well. Unfortunately, they chose not to back-track the aircraft as had been briefed so it took off from ahead of us and went away. We still got some good shots and, while it got airborne very quickly, it got to a certain distance when it seemed like it had stopped moving.

Then, it was time to go. We wrapped up and got on our way. I actually was back at home a little ahead of my normal time to get up so I did my normal routine and headed in to the office. It would be fair to say that I was not at my most perky that day!

Inflatable Hangar for Solar Impulse

Leave a reply

Solar Impulse was on the ground at Moffett for over a week while they waited for a good weather window for the next leg to Phoenix. They kindly invited me to go and have a look around in the more relaxed time compared to the arrival! The hangar was located on the apron at Moffett and they weren’t able to have a secure way to have visitors so, sadly, they could not have everything open to the public.

The hangar itself was pretty hot. It was white so reflective but it still warmed up quickly in the sun. The batteries were the only part of the aircraft for which this was a problem so they were permanently connected to air conditioning packs that kept them at the required temperature. I was a touch jealous.

The aircraft fitted snugly into the hangar given that it was custom designed. The air data boom had to be folded out of the way thought. The maintenance team were pretty busy checking out systems ready for the next leg whenever it would occur. Meanwhile, media attention was high and I wasn’t the only one there. A local TV crew were conducting interviews with Bertrand. When they had finished, he was happy to chat for a while.

The team were very generous with time and access but were very nervous about touching the aircraft itself. I wasn’t about to upset them so managed to get what I needed without causing any trouble.

Add an Ilyushin to the Recent Visitors

There have been a bunch of AN124s popping in to Moffett Field recently, one of which I saw while at the Solar Impulse arrival event. When I went back for the departure (which I covered for Global Aviation Resource in this article), I was surprised to see another freighter from the old Eastern Bloc. At his one was a more recent version though. It was an Ilyushin IL-76 but one that is fitted with the PS90 engine. It had been brought in to transport the ground crew and their gear for Solar Impulse. They were heading to Phoenix next and, since it was a short flight, everything needed to move quickly.

I didn’t get a great chance to photograph the plane. It was a long way up the ramp and there were too many lights between us to make for a great shot. However, I got what I could. My friend Hayman works nearby and he was able to get the departure later in the morning. I’m not jealous…

Solar Impulse and Shooting at Midnight

Leave a reply

The round the world trip of Solar Impulse, the solar powered aircraft conceived of by Bertrand Piccard and built/flown by him and Andre Borschberg, resumed its journey after an enforced stay in Hawaii while they dealt with some overheating issues with the batteries. By the time the batteries were fixed, it was too late in the year to continue. The aircraft charges its batteries during the day and uses them at night. If the day is shorter and the night longer, the flight is not sustainable. The arrival of spring meant they could resume the trip.

Originally the leg from Hawaii to the continental US was supposed to go to Phoenix. The break meant they came up with a revised route which included a stop in the Bay Area at Moffett Field in Mountain View. This meant I could cover it for Global Aviation Resource. There are two articles I prepared which you can see here and here.

The arrival was scheduled for about midnight. Late landings and early departures are scheduled to provide the calmest conditions. The very high aspect ratio, lightweight airframe is sensitive to turbulence. It also is easier to schedule a very slow aircraft in to the air traffic patterns during the night. While the time moved around a bit, it ended up being pretty much as expected. This brought the issue of how to shoot an aircraft at midnight.

I took a second shooter with me in the person of Hayman Tam. I wanted stills and video for the story and can’t get both at once so we worked on it together. He would focus on stills and I would get video. I would also get some stills too. The plane is sufficiently slow that you can get both for most situations apart from the landing itself. It didn’t hurt that Hayman had just taken delivery of his D500 which should be a lot better in low light.

I was mounting my camera and the 100-400 on a gimbal mount to steady it for video. This was also helpful for getting stills. Not ideal but better than nothing. I was at the max ISO for my camera of 12,800 (excluding the extended ranges) with -1 to -2 in exposure compensation. Even so, it was still a very slow shutter speed. Some bursts of shooting were necessary to get a reasonable shot. Fortunately the aircraft has a lot of lights of its own otherwise there wouldn’t be much to see. It’s a shame my new bodies hadn’t arrived at the time as they might have been able to get better results. Even so, I was quite pleased with what I got considering that I was shooting in the darkest conditions I have ever tried for a plane.
