RTL-SDR stuff is pretty popular, but plugging one into an RPi just doesn't feel like much of an accomplishment on the RPi front.

What would impress me would be two SDRs, one monitoring ADS-B and the other tuned to VHF, pulling down the ATC radio transmissions, recognizing the speech, deducing the tail numbers, and then visually associating them with the ADS-B traces on the map. Now that would be impressive! I've had VHF and ADS-B on my roof for the past few years but never got around to doing the speech parsing.
Since I'm in lockdown I have a lot of time on my hands to break out my soldering iron and more hardware. ;)
Couple other sources:

- Sound detection/recognition/localization - Could correlate with ADSB to label sounds with known airframes to help train an identification model
