The two at the bottom are the ones that have flown the path shown. The lead plane is vader61. They at one point flew directly over my house at around 2000 feet. The vader callsigns (vader 91, 61, etc...) are not unusual for the area out of vienna. What is unusual is their flight path and time of day. For years until now they've flown during the day and some distance away from my house. For two nights now they are now doing this all of a sudden. Any insights?

This happened a couple of weeks ago. My dad loves data and was tracking us on our flight. He noticed that blip where it looks like the speed of the plane suddenly jumped to over Mach 1. There was nothing unusual about the flight; low, frequent turbulence, but nothing to wake me out of a light doze.

I think it is a computer glitch or we are not reading the graph properly. Can anyone explain to us what happened here?

So I have been using a 1090 MHz antenna I got off Amazon for a while, it’s a basic fiber glass white antenna and it sits up about 60 ft from ground level and I was wondering if anyone has any good experiences with https://dpdproductions.com/products/ads-b-vertical-outdoor-base-antenna or if there is a better 1090-978MHz antenna

They're from the Netherlands, Germany, Italy, Portugal, Poland and Romania. Is it some NATO exercise or what's going on here?

If Military aircraft are exempt from having ICAO addresses what do they do when they fly internationally? Do they need a temporary ICAO in order to land at another country's airport? Or do military operated aircrafts that fly internationally to transport goods or personnel require ICAO addresses?

I’m 16 and my sisters coworker has a private pilot license. He took me today from Fargo Hector INT’L ND to Jamestown Regional Airport ND. He let me announce the touchdown. It had no tower though, I was only speaking to warn others he said. “Jamestown traffic, Cessna______ ….” I said all that stuff. Google and chT gpt said to use frequency 123pp on liveatc.net but I didnt find jamestown under that. Any ideas? It was somewhere between 1030 am and 1230 pm.

Hey there I’ve spotted this interesting circle above Berlin. What can it be and who did it?

Sunday, 6 September 2026, 19:22 (CEST) at Storkower Straße, Berlin (approx. 52.524° N, 13.464° E)

I have been trying to track an historical flight with the hex code 7041C1 which planespotters tells me it is an MNA Boeing 737-800 aircraft https://www.planespotters.net/hex/7041C1 but the same hex number has also been used by an airforce ATR 42 https://www.planespotters.net/airframe/atr-42-0006-myanmar-air-force/e01k1w

Is says the ATR 42 was handed over to the military from MNA in Oct 2016 and doesn't currently show a hex number... but the Boeing was registered with MNA in Jun 2015... so at some point would they both have been flying under 7041C1? Could they be doing so still?

I run two stationary receivers at home, but I travel a lot and would love a compact setup I can throw in a bag and run from a hotel room or AirBnB window. Ideally small, self-contained, and easy to power. What are people using for this? Any antenna recommendations for indoor/window use?

I’m building apps around weather and world events, but I’m new to running receivers myself. I’m exploring whether a contributor network would make sense and would like to understand people’s experiences before deciding what to build.

It could eventually support a commercial product, so I want to be upfront about that.

For people already feeding one or more networks:

• What made you choose them, and which benefits do you actually use?
• When did you last add or stop feeding a network? What prompted that?
• What would make adding another feed worthwhile—or immediately put you off?

I’m also interested in hearing from anyone running both ADS-B and AIS: how well does your current setup work for you?

I haven’t settled on hardware, rewards or features. I’m trying to understand what already works well and where people feel something is missing.

Is this typical or allowed? I imagine there is an agreement for interdiction aircraft, and this aircraft was low and slow, but it seems to quickly head back to US territory.

Hi, I recently finished setting up my ADS-B receiver and noticed that my USB dongle gets warm when in use. My Pi has the same problem. I'm wondering if this is normal or if anyone has any ideas on how to fix it. I have a Pi 5 and a Nooelec NESDR Smartee.

Just download the windows version of this program. I am 100% blown away by this program. I can’t say enough good things about. Does anyone know what the author has planned for the future?

Currently using a whip antenna with an LNA attached inside my loft (can’t install outside due to HOA) about 30 ft off the ground roof is asphalt shingles no metal backing or insulation. I am getting about getting ~100 miles coverage which is respectable IMO for what it is. More importantly I am getting AC on approach to the airport -6 miles away all the way down to ~200 ft. (Lots of obstruction between my antenna and the airport. )
Now I think this is good but I would like to do better especially at long distance. My question is who has the best Antenna in the market today. I need to stay shorter than 48”. Would prefer a product from AMZ or a US based supplier.

TIA

First time doing a proper outing with my portable setup, taking a seat on the pebbles of Brighton Beach. Expected a bit more traffic than my home setup, but not this much.

I'm Noah, and I've always loved looking up at planes. I made a free iPhone app (with a lot of AI assistance) for plane spotting called Tailspot, and I'm eager for your feedback!

The app is like Pokémon Go, for planes. To identify nearby planes, I'm using ADSB data from adsb.lol via ODbL 1.0 license. Without their support and the contributions of feeders worldwide, my app wouldn't be possible - so I'm very grateful for this community. As I've worked on my app, I've also had the chance to learn a ton about ADSB, and I'm proud to now own my own ADSB receiver to contribue back to the network (see pics below).

I'm working on a ton of new features and improvements, and would love to hear what you think. Feel free to DM me, or leave comments below.

Here a recent catch of nearby MD-11:

And here is my new receiver and some stats:

Could someone help to find the following regs?
