Sometimes you see a glimpse of the future 1890 envisioned for 2020.
Still can’t believe I caught this collection of aircraft in one relatively constrained frame on ADSB exchange; December 1 2020.
That’s a single-engine GA plane, a helicopter, some kind of Rutanmobile, and a U2.

Badge unlocked... used ADSB for the first time to confirm a C-17 spotting. Now I have to collect more exotic spottings.

You can run your own ADSB receiver with a Raspberry Pi and a cheap $20 usb dongle if you're interested rtl-sdr.com/adsb-aircraft-
