(11/05/1997) --- STS-87 Payload Specialist Leonid Kadenyuk, at right, of the National Space Agency of Ukraine (NSAU) is assisted into his orange launch and entry spacesuit ensemble by NASA Suit Technician Al Rochford, at left, before participating in Terminal Countdown Demonstration Test (TCDT) activities. The crew of the STS-87 mission is scheduled for launch Nov. 19 aboard the Space Shuttle Columbia. The TCDT is held at KSC prior to each Space Shuttle flight providing the crew of each mission opportunities to participate in simulated countdown activities. The TCDT ends with a mock launch countdown culminating in a simulated main engine cut-off. The crew also spends time undergoing emergency egress training exercises at the pad and has an opportunity to view and inspect the payloads in the orbiter's payload bay
