1. if there are no pads for he remaining boosters why havent most of

been scrapped? or does the air force still have a launch pad for them
somewhere like vandenberg?

2. although whats the problem with launching out of a silo? was
recently
in the one at tuscon, it gave awesome access to the booster and
payload.

so why couldnt they have been silo launched?

1. It was SLC-4W, but that was decommissioned. It costs nothing to
leave the boosters as is.

2. No it doesn't give good access to a spacecraft, only to a
warhead. vehicles with a spacecraft are taller and would extend out
the silo. Also, the launch environment is more harsh than a pad.
