146/AVRO RJ. Before that, Shorts 360, Jetstream 31/32, Fokker F27, HS121 for a short period, 737-400, and a brief gig on a North American B25.
And the F100 was indeed a fine ship, although I never got to fly it. Jumpseated in it about a thousand times though, always wished I had had the chance to fly it...
