Sometimes I feel lucky that human's electromagnetic spectrum perception is very limited to the so called "visible spectrum". Imaging alien species that evolved to perceive a wider electromagnetic spectrum, the earth must look like a disco ball when their spaceship approaches.

Much like we're lucky to have eyes that happen to see the sun's strongest frequencies?

Im surprised to see military traffic over the US. They tend to fly with ADSB out turned off and have an agreement with FAA to be able to do that. Also surprised to see gliders who generally don’t broadcast ADSB out. In the US, we are required to have ADSB out within most controlled airspace and within the mode C veil of a major airport (within 30nm and up to 10,000 MSL). So most GA planes have it but remote areas hav…

Fighters often don't have ADS-B, but there are lots of other military aircraft that routinely use it (transports, etc.). Go to https://globe.adsbexchange.com and press U to show only military.

I'd read about small retro reflectors they bolt on when not in combat so the stealth fighters will show on domestic radars

I started playing around with ADS-B and military aircraft are all over the place, at least on the east coast of the USA.

In fact, this Seahawk just flew over: https://globe.airplanes.live/?icao=ae6904

My town, north of Dayton, OH was recently overflown by a group of fighters (I believe F-18's). I was surprised that they didn't appear on the ADS-B tracker site I ran inside and looked at. I guess it makes sense.

I'm just a couple of miles from DAY and see a lot of traffic every day. It would be interesting to know how military aircraft like that coordinate with civilian air traffic control.

(I like to listen to Dayton approach while watching an ADS-B tracker site. I enjoy seeing the traffic fly over my neighborhood. I find it oddly amusing to look up at a plane I just heard getting clearance to land knowing that I just heard the voice of somebody up there thru my speakers. I don't know why it's so pleasing...)

The one glider path over the LAX area is interesting.

What was going on there?

I tracked, briefly, a F15E flying past yesterday.
