Airports take off and land into the wind, so when the wind changes, the paths over O'Fallon change too.

Live planes move along their real tracks: pink is low (under 3,000 feet, with altitude in hundreds of feet), navy is climbing or descending, gray is cruising high, green is a helicopter. Gold arrows show which way each airport is landing. Blue circles are airports with control towers. The shaded paths come from weeks of recorded flights: the darker the shading, the more planes fly there. Street map: OpenFreeMap, © OpenStreetMap contributors.

Arriving planes don’t fly straight to the runway. Controllers line them up like cars merging onto a highway, often 10 to 20 miles or more from the airport, and fly them along the side of the airport before turning them toward the runway. That is why a town several miles from an airport can sit right under the line of arriving planes, and why it changes when the airport switches direction.

Flight paths over O'Fallon: what the recorded flights show

We’ve recorded months of flights below 10,000 feet over this area. Here’s what they show for O'Fallon, and which way the wind sets the runways at each nearby airport. These are averages: any single day can be quieter or busier.

  • Aircraft rarely fly right over the center of O'Fallon: under a minute a day on average.
  • There’s no regular flight path within about 5 miles: most planes you see are passing at a distance or higher up.

Which way the wind sets the runways

  • Spirit of St Louis (SUS), 10.6 miles south-southeast: over the past year, whenever there was a breeze, it favored landing toward the west (runways 26L and 26R) 59% of the time and toward the east (runways 8L and 8R) 41%.
  • St. Louis Lambert International (STL), 18.3 miles east-southeast: over the past year, whenever there was a breeze, it favored landing toward the southwest (runway 24) 29% of the time and toward the southeast (runways 12L and 12R) 23%.

Estimated from the past year’s hourly winds (Nov 2025 to Oct 2026), counting the hours with at least a light breeze. The wind leads, but controllers also weigh noise rules, traffic and runway work, so the runway in use doesn’t always match.

Why the flight paths over O'Fallon change

The wind

Airports use the runway that points most into the wind. When the wind swings around, arrivals and departures flip to the other end of the runway, and planes can start crossing a different part of O'Fallon. That often happens when a front or a line of storms moves through.

Storms

Controllers steer planes around thunderstorms, so on stormy afternoons flights can show up where you normally never see them, sometimes lower and closer together than usual.

Busy times

At busy times, controllers space arrivals a few miles apart and may extend the line of planes farther out, which can stretch the arrival path over more neighborhoods.

Training and small planes

Smaller airports nearby are home to flight schools. Student pilots practice takeoffs, landings and approaches, so you may see the same small plane circle back again and again.

Questions about aircraft noise in O'Fallon

Aircraft noise is handled by the airport, not by air traffic control. Each airport (usually run by a city, county or airport authority) has its own noise office and wants to hear about specific flights, so note the date and time. The airports near O'Fallon are:

To find the right noise office, search the airport’s name with the word “noise,” or use the FAA’s airport locator. If the airport can’t help, the FAA’s noise ombudsman can. FAA: Noise complaints and inquiries → · Find your airport’s noise office, and what helps at home →

Common questions

Which way does STL usually land?

Over the past year, whenever there was a breeze, the wind favored St. Louis Lambert International landing toward the southwest (runway 24) 29% of the time and toward the southeast (runways 12L and 12R) 23%. Planes take off and land into the wind, so the direction flips when the wind does.

Why are planes flying so low over O'Fallon?

Planes low over O'Fallon are usually landing at or taking off from one of the nearby airports, such as Spirit of St Louis (SUS), 11 miles away. Air traffic controllers keep every one of them safely separated from the others.

Why are there more planes over O'Fallon some days?

Mostly because of the wind. Airports take off and land into the wind, so a wind shift can send arrivals or departures over different neighborhoods. Storms and busy travel days can also move or stretch the usual paths.

Which airport are the planes over O'Fallon going to?

The closest airports with control towers are Spirit of St Louis (SUS), St. Louis Lambert International (STL). Low planes are usually using one of these; higher jets are often passing over on the way somewhere else.

Who do I contact about airplane noise in O'Fallon?

The noise office of the airport the plane was using, not the control tower. Have the date and time ready. If the airport can't help, the FAA's noise ombudsman takes inquiries through faa.gov/noise.
