Question: After the SkyWest airliner touched down, the Airport Movement Area Safety System (AMASS) alerted and the air traffic controller transmitted "Hold, Hold, Hold" to the SkyWest flight crew in an attempt to stop the aircraft short of runway 1L.

As this was occurring, the captain of Republic Airlines flight 4912 took control of the aircraft from the first officer, realized the aircraft was traveling too fast to stop, and initiated an immediate takeoff. According to the crew of SkyWest 5741, the Republic Airlines aircraft overflew theirs by 30 to 50 feet. The Federal Aviation Administration has categorized the incident as an operational error.
