On Friday, November 13, 2026, the FAA ordered a nationwide ground stop at 3:54 p.m. Eastern. We wanted to see what that looked like from the sky, so we used open flight-tracking data to count every airline takeoff in the contiguous U.S. that day and set it against a normal Friday a week earlier.
What we found
- Takeoffs nearly stopped. From 4 to 7 p.m. Eastern we tracked 84 airline takeoffs, compared with 4,080 on November 6, about 2% of a normal afternoon.
- The sky emptied within hours. Airline flights in the air fell from 2,407 when the stop began to 335 by 7 p.m. On a normal Friday there were 2,991 in the air at 7 p.m.
- Some departures continued. The FAA released some flights case by case, including Pacific flights from San Francisco and transatlantic flights from the East Coast.
Press play on the map to watch it happen, and switch on the normal Friday to compare.
About the data
The counts come from ADS-B signals that volunteers receive and share through adsb.lol. They show tracked flights, not official totals, so rural areas may be undercounted. The full method, the code, and the data are in the download below.
