Stevens R. 1963 Jan. 10 Frankfurt to Munich 12:00 noon. Came down through heavy overcast. Ceiling perhaps 500-1000 ft. but plane zeroed in on runway in good style. Trees at 4 mi. only dimly visible.

Soon climbed above clouds to altitude of 29,000 ft. for crossing Alps. Some high peaks, like great icebergs, projected above the clouds. Still higher were streams of white cirrus. Sun bright. Bumpy over Alps. 2:00 pm. Solid sheet of white below. We have ascended above the uppermost cloud layer. 2:15 pm. Just crossed border of Austria and Yugoslavia at 33,000 ft. Captain tells us we will fly over Belgrade and thence along the Aegean Sea to Istanbul. Visibility there to be quite good with possibility, however, of rain showers. Temp. expected 48°. We continue with solid cloud blanket below. Can see nothing below. 3:10 pm. Aegean Sea. Cloud cover breaking up. Plan now shifts direction to NE. Time change 5:50 pm. Landed at Istanbul.
