This altitude change will have a detrimental effect on traffic between Southwestern Indiana, Kentucky and Indianapolis. Not long after 9/11/2001, there was a "Temporary Flying Restriction" in this area, and the operations at Crane were unchanged. During this multi-year "temporary" restriction, there were many, many inadvertent violators of this area, mostly because it encompassed quite a bit more altitude than the Restricted area. While I don't believe the 1 mile radius change will affect as many aviators, the altitude limit will ABSOLUTELY affect many pilots. The state of Indiana finally managed to get an airline to start flying between Evansville, Indiana and Indianapoils. This airline (and many other pilots) uses the exact route over Crane NSWC, and is unable to fly above 9000 feet, so this change will remove 1/3 of the airspace available to them. During conditions where icing conditions exist, they will be unable to descend if they encounter hazardous ice above 5000 feet -- EXACTLY where they will be REQUIRED to fly if this is enacted. PLEASE don't raise the vertical limits of this Restricted area to needlessly endanger pilots and passengers. PLEASE find a way to keep this area below 2900 feet MSL. Staying below this altitude will be extremely helpful for pilots, passengers, and the general public.
