Birds Eye 3-68, 21 May-10 June 1968.
BIRDS EYE 3-68 was a regularly scheduled Arctic Ocean ice reconnaissance mission covering oceanic areas south of 81 degrees between Greenland and Norway from 21 May through 10 June 1968. Ice observations contained in this report were made under daylight conditions with very poor flying conditions du...
