In reply to Archmagos_Dominus:
Not rockets but aviation related. I've finally got round to hooking up an RTL-SDR unit with a 1090 MHz notch filter and some ADS-B code. I've started putting some software on top of it all to predict the point of closest approach to the Wintertree bunker along with the time. I'm impressed at the range of it - the generic antenna is in a west facing window and can hear from flights all the way over the lakes; I'll get a proper antenna up in to the rafters.
Next up is a go at triangulating the cloud base with a pair of cameras to squelch anything not likely to be visible.
Presumably Starship is going to have to carry a transponder for Earth to Earth flights (if you believe in those), so I've got a few years yet to get an Alt-Az mount in to track it with a decent zoom lens before it starts making overflights on the way to Europe...
