Narrative:

Aircraft was climbing to FL220 but was stopped by radar position at FL200 for nwbound traffic. Aircraft requested FL200 as a final, so radar approved and issued FL200 as final altitude. Many aircraft along this swbound route of flight were deviating for WX, and other aircraft were requesting different altitude for chop. Our aircraft at FL200 swbound was handed off and switched to the appropriate sector 20+ mi before crossing the sector boundary. Upon crossing the sector boundary aircraft at FL200 entered ft knox restr area airspace. Normally ft knox is always active 10000 ft MSL and below, but not this day. Radar person noticed the airspace violation after the aircraft was 10+ mi in the restr area.

Title: ZID ASSOCIATED CTLR OBSERVES ACFT TRANSITION INTO ANOTHER CTLR'S AIRSPACE AT A NON COORD ALT PENETRATING RESTR AIRSPACE.

Narrative: ACFT WAS CLBING TO FL220 BUT WAS STOPPED BY RADAR POS AT FL200 FOR NWBOUND TFC. ACFT REQUESTED FL200 AS A FINAL, SO RADAR APPROVED AND ISSUED FL200 AS FINAL ALT. MANY ACFT ALONG THIS SWBOUND RTE OF FLT WERE DEVIATING FOR WX, AND OTHER ACFT WERE REQUESTING DIFFERENT ALT FOR CHOP. OUR ACFT AT FL200 SWBOUND WAS HANDED OFF AND SWITCHED TO THE APPROPRIATE SECTOR 20+ MI BEFORE XING THE SECTOR BOUNDARY. UPON XING THE SECTOR BOUNDARY ACFT AT FL200 ENTERED FT KNOX RESTR AREA AIRSPACE. NORMALLY FT KNOX IS ALWAYS ACTIVE 10000 FT MSL AND BELOW, BUT NOT THIS DAY. RADAR PERSON NOTICED THE AIRSPACE VIOLATION AFTER THE ACFT WAS 10+ MI IN THE RESTR AREA.
