Oklahoma City Fog Creates Flight Delays, Diversions, and Spectacular Photos

Iron Men: Morning Fog

Extremely dense fog choked air travel in and out of Oklahoma City Sunday night and Monday morning, leaving hundreds of people waiting for severely delayed flights to and from Oklahoma's largest city.
Cool, moist air and a lack of wind allowed the fog to form quickly Sunday evening. By 9:14 p.m. CST, the city's main airport, Will Rogers World Airport, reported visibility of one-quarter of a mile.
The visibility remained that bad or worse all night and most of Monday morning. Visibility dropped to one-sixteenth of a mile shortly before midnight and stayed that way until just before 10 a.m. local time.
Because of the extremely low visibility, most flights in and out of Will Rogers World Airport were severely delayed, and in some cases, canceled. Some incoming flights were diverted because the fog made it too dangerous to land.
The airport's official website showed departure delays of more than 5 hours for most early morning flights – that is, the ones that weren't canceled outright.
Arriving flights faced severe difficulties as well. For instance, United Airlines Flight 5902, scheduled to leave Denver International Airport at 9:04 p.m. Sunday, did not leave Denver until more than 11 hours later; it was then diverted to Dallas-Fort Worth International Airport because of the weather in Oklahoma City.
