Speaking from a humble SLF viewpoint, I'm a little disturbed that the disabled bizjet is seen by most as an 'obstacle', to be compared with repair works or a hole in the runway. If I were a passenger on a plane that broke down and failed to clear the runway, I wouldn't be cheered to know that heavy jets would be landing over me or behind me, and that all I could do was trust that they wouldn't hit any 'bits' on the runway (say, left by a plane that had a problem on landing) and blew a tyre. Isn't there an issue of passenger protection here?
