One reason why
the steady increase in

activirY
overflights were stopped was
ability to track and engage U-2s, as
owning five U-2s. By 1968
were keeping a close watch on
and actively tracked U-2s as soon as
they became airborne. me u-hs then had to face a growing PRC air
defense system that not only consisted of SA-2 missiles but also the
r"----1fast and high-flying MiG-21. MiG-21 pilots had become
adept at the power-zoom technique and w re threatening almost every
U-2 mission. The risks to U-2s now seemed too great.°
The decision to end Asian overflights was also rooted in the
Johnson administration's change in its whole approach to the war in
Indochina in the spring of 1968. On 31 March 1968, the President
limited the bombing of North Vietnam in order to improve the
chances for peace talks. The end of flights over
T-lwas viewed as another way to improve me peace process.
