Audio shows an air traffic controller canceling the take off clearance for the AA flight 2134 as the private King Air plane was set to land on an intersecting runway at 10:21am local time.
Audio shows nothing, it may record/tell, but it SHOWS nothing.
Runway Status Lights (RWSL) are operational at 20 airports in the United States. This system is designed to enhance runway safety by providing automated, real-time alerts to pilots and ground vehicle operators about potential runway conflicts. Here is the complete list of U.S. airports equipped with RWSL:
Baltimore-Washington International Airport (BWI) Boston Logan International Airport (BOS) Charlotte Douglas International Airport (CLT) Chicago O'Hare International Airport (ORD) Dallas-Fort Worth International Airport (DFW) Detroit Metropolitan Wayne County Airport (DTW) Fort Lauderdale/Hollywood International Airport (FLL) George Bush Intercontinental Airport (IAH) John F. Kennedy International Airport (JFK) LaGuardia Airport (LGA) Las Vegas McCarran International Airport (LAS) Los Angeles International Airport (LAX) Minneapolis-St. Paul International Airport (MSP) Newark Liberty International Airport (EWR) Orlando International Airport (MCO) Phoenix Sky Harbor International Airport (PHX) San Diego International Airport (SAN) San Francisco International Airport (SFO) Seattle-Tacoma International Airport (SEA) Washington Dulles International Airport (IAD)
If both of those runways had RWSL then the jet taking off would have had a sequence of red centerline lights. The ATC controller has no direct control of that system.
