Your favorite ship flown during your pilot career

Please feel free to share the most desired ship you had the opportunity to fly during your career as a pilot, or even if you had not been a pilot at the time.

My most favorite ship I have flown so far has been the MD-500. I had the opportunity to fly it back in 2007 when I wasn't a rated pilot yet. It was a lucky scenario really. The pilot who flew in the aircraft with me was the brother of a maintenance test pilot I knew in the military. What a great ship to fly; Fast, agile, very maneuverable, and all around just a fun ship to fly! I call it the porshe of the skies!
