Gutted.
Alex taught me to fly the 350 and a damn fine job he did. More than that though, he mentored me (including making perfectly clear when I'd stuffed up and needed to pull my socks up, but always in private) and helped whenever and however he could. He'd literally give you the shirt off his back. Totally free of any bullshine, generous and considerate to a fault, a real friend. The world is a lesser place.
