I am about 8 miles away from KORD airport. With my little indoor antenna that is in the window facing away from the airport, my Skyaware page shows approximately 20 aircraft at any given time.
This morning when I loaded my page, it was suddenly tracking well over 100 aircraft with many of the positions in the chart showing up as “ground”. The map was also showing a ton of aircraft on the ground at O’Hare. A few minutes later, all of the ground positions disappeared and the maps went back to normal showing only 20 or so aircraft in the air.
Anyone have any idea what possibly could have happened during these few minutes? It was pretty cool while it lasted. Thanks.
