PLANEFAGS!
Had recent overflight of a large twin turboprop with a large appendage under the right wing inside engine nacelle. Could have been a small plane or missile? It was the sound of the engines that made me look, not some twin citation, but big props.
Binocs too far away, doesn't/didn't show on ADSB. I'd guess it to be 12-15,000', maybe 180-200kts. Light colored, off white?
