This is a CIA History Staff monograph by Gregory W. Pedlow and Donald E. Welzenbach, published in Washington in 1992 and approved for release in 2011. It covers the CIA's manned overhead reconnaissance program from 1954 to 1974, which developed and flew the U-2 and the A-12 OXCART. It traces the U-2's development, the overflights of the Soviet Union, the downing of Francis Gary Powers on 1 May 1960, and later operations. One section is titled U-2s, UFOs, and Operation BLUE BOOK.

photointerpreters to use in searching subsequent overhead photogra-
phy for similar installations:3
The two proposed overflights that would cover the northern rail-
road lines received the strongest consideration. Both plans contained
new features. Operation TIME STEP called for a U-2 to take off from
the USAF base at Thule, Greenland,
The aircraft would then fly over Novaya
Zemlya on its way to cover the railroad lines from the Polyarnyy Ural
Mountains to Kotlas.
Tother proposed overflight, Operation GRAND
JLHIV1, was we first U-2 mission planned to transit the Soviet Union;
all previous missions had penetrated not more than halfway and then
left in the general direction from which they came. GRAND SLAM
proposed to fly across the Soviet Union from south to north, departing

fled the White House that neither mission could be flown before
19 April. Once the maneuvers ended, bad weather over the Soviet
Union kept the mission from taking place when it was originally
scheduled. Richard Bissell, therefore, asked President Eisenhower for
more time, and, on 25 April, General Goodpaster relayed the
President's instructions to Bissell that "one additional operation may
be undertaken, provided it is carried out prior to May 1. No operation
is to be carried out after May 1." 24 The President did not want to fly
missions any later than that because the Paris Summit was scheduled
to be g in on 16 May 1960.
By this time, CIA planners were concentrating on Operation
GRAND SLAM as the most likely route for the proposed mission be-
cause it offered the best chance of photographing suspected locations
