With a basic RTLSDR and a random small TV antenna (nothing optimized for this use case), from my apartment I've picked up airplanes that were at 40000ft and at a distance of ~ 100 km (62 miles).
Optimizing the antenna and the hardware (and using a lot less cable for the antenna than I have) would probably increase that significantly.
