You’re sitting on your porch, or maybe stuck in traffic, and you hear that low-frequency rumble. You look up. There’s a silver speck trailing a white line across the blue. It’s easy to just call it a "plane" and move on, but honestly, there’s a whole digital world dedicated to answering exactly what planes are above me right now with startling precision.
It isn't magic. It's ADS-B.
Most people think radar is still the primary way we track aircraft. That's old school. While primary radar—the kind that bounces radio waves off a metal fuselage—still exists, modern aviation relies on Automatic Dependent Surveillance-Broadcast. Basically, the plane tells the world where it is. It broadcasts its GPS location, altitude, and velocity to anyone with a cheap antenna and an internet connection.
The Best Tools to See What's Overhead
If you want the quickest answer to what planes are above me right now, you’ve probably already heard of Flightradar24. It's the "household name" for a reason. They have the most polished interface. You open the app, it uses your phone's GPS, and suddenly you’re looking at an augmented reality (AR) view of the sky.
But here’s the thing. Flightradar24 filters stuff.
Because they are a massive commercial entity, they comply with certain "blocking" requests. If a billionaire doesn't want you seeing their private jet, or if a specific government tail number is sensitive, Flightradar24 might hide it or show it as "blocked."
That’s where ADSBexchange comes in.

I’m kinda obsessed with ADSBexchange because they don’t filter. It’s a community-driven project. They don't take "please hide my plane" requests from corporations. If a signal is being broadcast into public airspace, they show it. If you see a weird military tanker circling or a high-altitude surveillance drone, this is where you find it. The interface looks like something out of a 1990s hacker movie, but the data is raw and honest.
Then there's FlightAware. It's the suit-and-tie version. It’s great for checking if your aunt’s flight from Chicago is delayed, but it’s less about "sky watching" and more about logistics. It’s reliable, but maybe a bit boring if you're trying to identify the weird noisy helicopter that just rattled your windows.
Decoding the Symbols and Data
When you finally pull up a map to see what planes are above me right now, you’ll see a bunch of icons. Most are just little yellow or blue planes. But look closer.
The color usually indicates altitude. On many sites, yellow means it’s at cruising altitude (30,000+ feet), while green or white might mean it’s descending. If you see a icon that looks like a tiny toothpick with wings, that’s a private jet—something like a Gulfstream G650 or a Cessna Citation. Those guys are moving fast.
The "Squawk Code" is the most interesting bit of data you’ll find. It’s a four-digit transponder code.
- 7500: Hijacking (You almost never want to see this).
- 7600: Radio failure.
- 7700: General emergency.
If you ever see a plane icon flashing red on your screen with a 7700 code, you’re watching a real-time drama. Maybe it’s an engine issue or a medical emergency on board.

Why Some Planes Don't Show Up
You ever look up, see a massive C-17 Globemaster or a fighter jet, check your app, and see... nothing?
It's frustrating.
Military aircraft often fly with their transponders in "Mode S" or "ADS-B Out" turned off for operational security. They don't want every person with a smartphone knowing exactly where a B-2 Spirit is loitering. However, sometimes they leave them on during routine training missions or transport flights.
Also, small "General Aviation" planes—the tiny Cessnas and Pipers—don't always have the expensive hardware required for satellite tracking. They might show up on "MLAT" (Multilateration). This is a cool math trick where four or more ground receivers calculate the plane's position based on how long it takes the signal to reach each station. It's less accurate, and if there aren't enough receivers in your rural area, the plane simply vanishes from the digital map.
The Mystery of the "No Callsign" Aircraft
Sometimes you'll click an icon and it just says "N/A" or "No Callsign."
Creepy? Not really.

It’s usually just a glitch in the database or a newly registered aircraft that hasn't had its info updated in the global registry. Or, it’s a government "grey" plane. In the US, the FAA has a program called LADD (Limiting Aircraft Data Display). This allows owners to fly without their specific registration being broadcast to the public. You’ll see the plane’s position, but you won't know if it belongs to a tech mogul or a shell company for the DOJ.
How to Get Better at Identifying Planes
To really master knowing what planes are above me right now, you need to look at more than just the icon. Look at the altitude and the path.
If a plane is at 3,000 feet and flying in a perfect grid pattern, it’s probably doing aerial photography or LIDAR mapping. If it’s circling a specific neighborhood for an hour, it might be a police helicopter (look for the "N" number and Google it; many belong to local sheriff departments).
Check the "Ground Speed." If you see a plane at 35,000 feet doing 550 knots, that’s a standard commercial airliner like a Boeing 737 or an Airbus A320. If you see something at that same altitude doing 150 knots, you’re looking at a glitch—or perhaps a very strong headwind hitting a smaller turboprop.
Actionable Steps for Skywatchers
If you’re serious about this, don't just be a passive consumer of data.
- Use the AR Mode: Download the Flightradar24 app and hit the "AR" button in the top corner. Point your camera at the plane in the sky. It overlays the flight number and destination directly onto your camera feed. It’s the closest thing to having bionic eyes.
- Monitor "7700" Alerts: You can set up push notifications on most tracking apps to alert you when a plane nearby declares an emergency. It’s a fascinating, if sometimes intense, way to see how air traffic control handles crises.
- Check the Tail Number: Every aircraft has a "license plate." In the US, it starts with an N (like N12345). Type that number into the FAA Registry website. You can find out exactly who owns the plane, the year it was built, and what kind of engines it has.
- Listen to LiveATC: If you see a plane doing something weird, go to LiveATC.net. You can listen to the actual radio transmissions between the pilot and the tower. It’s all public record. If a pilot is reporting "birds on the runway" or "heavy turbulence at 20,000," you’ll hear it live.
- Build Your Own Receiver: If you live in a "dead zone" where planes don't show up on apps, you can buy a $30 SDR (Software Defined Radio) USB stick and a small antenna. Plug it into a Raspberry Pi, and you can feed data to these global networks. They’ll usually give you a free "Business" or "Enterprise" subscription in exchange for the data.
The sky isn't just an empty void. It's a crowded, organized highway system. Once you start looking at the data, you’ll never look at a white contrail the same way again.
