What does "ORDER" mean

What does it mean when “ORDER” is listed as origin or destination?

Please give an example. My first thought is that “ORDER” is a way point because it is 5 letters long.

check out n787RR

Just what I thought. The aircraft is flying to a way point named ORDER - see flightaware.com/live/flight/N787 … KTUS/ORDER

After doing whatever it’s doing (more than likely flight test of an engine in this case) it picks up a flight plan that takes it back to TUS from ORDER - see flightaware.com/live/flight/N787 … ORDER/KTUS

Here is the info for the waypoint “ORDER” - airnav.com/airspace/fix/ORDER

Thank you
