Four airports serving Washington, Baltimore and Richmond halted all flights tonight (Friday) for over an hour because of a strong chemical smell that was impeding air traffic controllers, according to the Federal Aviation Administration.

The ground stop affected Reagan National Airport, Washington Dulles International Airport, Baltimore-Washington International Airport and Richmond International Airport, FAA Secretary Sean Duffy said. The declaration caused flight delays to soar to roughly two hours across some of the busiest airports in the country.

Clocks will skip ahead an hour at 2 a.m. Sunday for daylight saving time in most of the U.S., creating a 23-hour day that throws off sleep schedules, plunges early-morning dog walks into darkness and inspires millions of complaints.

In Virginia, the push to end the twice-a-year clock change has stalled. A Virginia House committee this week recommended dropping the issue until 2027. The state is one of half a dozen that have adopted bills to switch to permanent standard time in one legislative chamber in the last two years, though Virginia’s measure included a caveat: the change would only take effect if Maryland and Washington, D.C., also made the move.
