Long haul,
The Rescue vehicles with the tracked, tank-like wheels you see in the photos were ordered after the Saab 340 crash about ten years ago, when they had trouble navigating through the thick mud prevalent in the fields around the airport. Whoever decided to make that investment may have saved someone's life today.
When I saw the damage, the only thing that made me give any credence to the denials of any deaths, was the lack of helicopters. At a major airport in the US, lifeflight helicopters would have been all over it. Not just some tracked vehicle. I still assume that the television cameras just arrived too late for the helicopters. Was that tracked vehicle really all they had?
