True, 16-blades.
One of their pilots was on a two-day trip this summer as my First Officer. The hurricane season began very early this summer.
In the guy's Hurricane Hunter, Air Force Reserve squadron at Keesler AFB, Biloxi (the town was one of several which were destroyed by Katrina), MS, they fly the older three-man c0ckp1t and also the newer J model, with the automated systems and EFIS. The guy also flew the B-52 and the Special Operations MC-130 (they sometimes must destroy navigational charts after a mission-you should hear about the squadron which was based in Taiwan many years ago...).
The RAF flies the J model, doesn't it?
