Quite sincerely, I think every aircraft that flies today has a limitation. I spent ten years flying on the Hercules with Pacific Western, and we flew all over the world. Some days you could fly and some days you couldn't. We've been in the Arctic when it's 60 below and the wind is blowing 50 miles an hour for five or six days. Could anybody fly? No.
I think every aircraft has some kind of limitation. Most of the concern that I continue to hear in my discussions with people is what we're going to do when it's really windy. They're worried about the wind.
I don't think there's as much of an issue with the cold. Some days you'll be able to fly the machines and some days you won't. There will just be days when it can happen.
How many days a year could you not fly? I don't know. There will be limitations when they cannot fly, but generally speaking, with today's equipment, today's avionics, today's satellite tracking, and all the communications between any aircraft that flies, they should be able to fly as many days as is physically possible.
