jimjim1 while relocating IT gear at work do you have to wait for someone from IEEE or FCC to come on-site, review your paperwork, you credentials, your work, and then test all of it?
The fact of how easy it is do some other thing in some other industry does not always translate to doing a complicated thing in aviation. In this case it might seem proper do devote all the resources to one runway, but this runway had other available approach alternatives and the weather was perfect. It would be like someone demand ALL cars be equipped with automated parallel parking gear because one driver drove his car into a wall. He could have picked another parking space, parked manually, tried again.
