John,
Your keen eyesight is admirable! The North County airspace is home turf to the guys at West palm Test Center, and the Comanche at Ft. Lauderdale was there for the AAAA convention (Army Aviation Association of America) last year.
The Fantail was at Paris doing those "Snap Turns" for the crowd. It was a real gas flying that airplane, and quite thrilling to see 125,000 people all turned eyes up to watch the demo. Talk about praying "Lord, please don't let me screw up!" It was actually 90 degrees of flat turn in 2 seconds at 120 knots to the left and 105 knots to the right.
Comanche is even better! Rus Stiles, John Dixson and I were the pilots on that show.
