The aluminum runway is a system that has been used primarily by the American military and NATO partners, as I said, for over 50 years. They land everything on it from jets through to heavy transport carrying up to 850,000 pounds.
The company that developed an aluminum runway for military use has now developed one for commercial use, which is twice as strong as the military version and has been designed ideally for locations where there are going to be limited maintenance capabilities. It's something that will be able to deal with permafrost issues, and it's going to last for years.
I took a group of people down to Twentynine Palms air marine training base to show them the runway that has been there for 48 years. Some of the panels on that runway are the same ones that were installed 48 years ago, so we know it's going to last.
The problem, thinking on the money side of it, is it's probably two to two and a half times as expensive as putting down an asphalt runway. However, over the course of 40 years, at about the 20-year mark, it becomes equal to an asphalt runway because you don't have to resurface it all the time. Over the course of 40 years or 50 years, of course, it's far cheaper and it's totally recyclable.
