Narrative:

Location: #1 for runway 17R. While holding short of runway 17R at approximately XX00Z due to WX a DC9 was observed landing over the top of one of our aircraft who was on the runway. The controller had cleared them onto the runway prior to stopping all departures. They then instructed that aircraft as well as all others to shut down their engines. While holding we observed a DC9 land on runway 17R over the top of an air carrier X aircraft. No one said anything and when I inquired, the tower on another frequency asked air carrier Y if they had landed on runway 17C. This was done on another frequency and I did not hear the response but did hear the controller give air carrier Y a phone number to contact. The air carrier X aircraft on the runway then asked to exit the runway and asked for the same phone number.
