Re: [SystemSafety] Chicago controller halts Delta jet's near-miss on takeoff: '1328, stop, stop stop!'

I can see how "3828" can be possibly confused with "1328". But ATC never uses flight numbers alone. One flight would be "Cactus 3828" and the other "Delta 1328". Unless the DL pilot used to work for SW, how could s/he not recognize the company part of the call sign?

Agree. Perhaps it is more properly termed a rare coincidence of call sign similarity.
