On a less bitter note, it looks like it might be a bit of a hot ship to handle at low speed, would it be able to get into Citation sized airfields.
You can always get an aircraft onto a landing field. Whether it's in a condition to fly out again is another matter.
What sort of altitude are they planning to fly this thing? Concorde was pretty much on its own up at FL600 where it didn't have to worry about other traffic, I'm guessing this will be flying lower
