	My understanding was that STS-11 was canned because of continuing
	problems with the Inertial Upper Stage (IUS) which is a VERY 
	different booster that the smaller Payload Assist Module (PAM).
	The top secret bird apparently is large enough to need a IUS
	instead of a PAM which is used on smaller payloads such as
	those deplyed on the pervious orbiter missions.
