Shuttle control is entirely by computer, pilot is "hands-off'.
Fred Haise demonstrated during and ALT test at Edwards in '76 or '77 what would happen
if a pilot interfered with the computer on approach and landing, he tried to make a stick adjustment
and banged down one side gear strut and almost hit the runway with a wing, kept quiet though.
Any flight trim from de-orbit is done by the computer firing short bursts from banks of
steering rockets on the nose - top bottom and sides, and on the Doghouse area on the aft structure,
again - top, bottom, and both sides near the vertical stabilizer.
You can see them in some pictures.
The first launch was the only time the external tank was painted white, for photograph appearance.
The size of the Shuttle is overwhelming, the US flag on the wing is 6 ft tall.
The external tank when transported on it's side is the hieght of a 3 story building,
The Solid Boosters are 12 ft. in diameter.
On the Launch Mount, the Tail Service Masts - they look like tombstones on each side of the
shuttle on either side of the aft structure - are the height of a 2 story building.
A Greyhound Bus will fit in the cargo bay with the doors closed, and enough room
is left to place a mini-van in there.
EDIT: Cliped from a data site -
Space Shuttle: The External Tank (ET) is sprayed with a foam that turns orange (or rust colored) as a result of ultraviolet exposure (from the sun). This exposure also hardens the foam, improving its insulating properties.
The External Tank on the first Shuttle mission was painted white to match the white color of the shuttle and solid rocket boosters. However, the extra weight only added needless weight to the system, therefore the External Tank was left unpainted in its now familiar rust color for all future missions.
