I was skimming through the RealATC videos on YouTube today and watched this one. In it there are two flights taking off from Chicago-Midway (KMDW); Delta flight DAL1328/DL1328 and SouthWest's SWA3828/WN3828. They are each taking off from crossing runways (4R and 31C). For some reason, even though SWA3828 is given clearance to take off, the Delta flight also starts its own rollout.
After the call to abort is given, both aircraft abort takeoff and are able to then safely leave their respective runways in order to taxi back to the proper starting point. One of the aircraft states it will need a few minutes to check for heated brakes. Then both aircraft state they will need to "call company" for some unspecified reason.
Why would both planes need to call company? My guess is to recalculate fuel used to determine if they will have enough fuel to continue the trip. Why else might they need to do so?
