FROM BRITAIN TO AMERICA AND BACK BY BALLOON

The great British dirigible, R-34, was the first lighter-than-air vessel

to cross the Atlantic. She left East Fortune, Scotland, July 2, 1919,

under command of Major Scott, and covered 3,200 miles to Mineola, Long

Island, in 4 days 12 hours 12 minutes. The return journey was made in 3

days 3 hours 3 minutes. Note the piles of hydrogen gas bottles needed to

replenish the gas supply.]
