KENNEDY SPACE CENTER, FLA. -- STS-111 Pilot Paul Lockhart poses for the camera before taking his turn at driving the M-113 armored personnel carrier during emergency egress training at the pad. The training is part of Terminal Countdown Demonstration Test activities at KSC. The TCDT also includes a simulated launch countdown. Known as Utilization Flight -2, the mission includes attaching a Canadian-built mobile base system to the International Space Station that will enable the Canadarm2 robotic arm to move along a railway on the Station's truss to build and maintain the outpost. The crew will also replace a faulty wrist/roll joint on the Canadarm2 as well as unload almost three tons of experiments and supplies from the Italian-built Multi-Purpose Logistics Module Leonardo. Launch of Space Shuttle Endeavour on mission STS-111 is scheduled for May 30, 2002
