1,000 drones used for Messi farewell show lead to NOTAM and flight holds at Aeroparque

A private sponsor funded a simultaneous deployment of 1,000 drones for the Messi farewell show at Estadio Monumental, costing about 100,000 dollars, and a NOTAM was issued to airlines and pilots notifying possible restrictions between 22:00 and 23:00.
At least three commercial flights to Aeroparque were forced to hold in a pattern for about 15 minutes while waiting for the airspace to be released, highlighting the operational impact of mass events near the main airport during peak demand hours.
Why it matters
The event shows how large-scale activities near an airport can affect airline operations during busy periods.
