Mystery Adelaide Stealth Bugsmasher
Been spending a few days in Adelaide and after sunset have been hearing a turboprop aircraft high above in the gloom. Caught my ear as it's using a low power setting - so not trying to go anywhere in a hurry. Keeps coming back every 5 minutes or so. Not an Orion as I know those things just retired, and it sounds different anyway. Staying with fellow aviators so we'd sit in the back yard drinking beers trying to eye it as it seemed a bit curious. Pretty obvious it's not flying with lights on - well, if they are they are rather dim and no strobes.
It's also not on Flightradar24.
The other night it the gloom before it got too dark we got a visual - single engine, probably a Caravan, doing racetracks maybe 10k' or a bit lower. Is this a normal Adelaide thing? Drilling holes in the sky high up going nowhere in particular??
