Airport Traffic Stopped After Strange Smell

A sharp chemical odor hit a Virginia air‑traffic control center, forcing the FAA to shut down three major airports in the Washington area. The incident began when controllers at Potomac Consolidated Terminal RADAR Approach Control could no longer work because the air smelled strongly of chemicals. This center manages the skies above many local airports, so its shutdown had a ripple effect.

Reagan Washington National Airport, Washington Dulles International Airport and Baltimore‑Washington International Airport all had to halt flights. Airlines reported that some planes were diverted due to the congestion created by the stop‑gap measures. The FAA moved many controllers to a training facility, but their radar coverage was limited, which means delays are expected even after normal operations resume. Flight tracking data shows that about 30 % of flights at Reagan were delayed on the day. The reduced radar scope and temporary relocation of staff are likely to keep delays in check for a while. The incident highlights how sensitive air‑traffic control is to environmental conditions. Even a single chemical scent can disrupt the complex system that keeps planes moving safely.
