The personal library fo former U.S. president Dwight Eisenhower:
"The Avro Arrow would have been the only aircraft of the day with the altitude capablility, the intercept capability to basically attack and destroy a U-2 . . . or to find out what the U-2 was really doing up there,"he said.
At the time, Washington was using U-2 aircraft to spy on countries around the globe but publicaly insisted they were only weather reconnaisance flights.
