Essentially we can do a lot of the same things, but in addition we do not have the requirement for a runway. We can operate from any place that's large enough to hold us and that has some fuel available. The infrastructure requirements are minimal; the crew can do whatever maintenance they need to do on the aircraft. If there were a tanker available, you could literally stay in the air for as long as you can stand it.
The aircraft has been tested to 120 degrees Fahrenheit; operationally it's been tested down to minus 69 degrees. It has already proven that it can operate in the extremes.
