English: In 1978, Ben Abruzzo, Maxie Anderson, and Larry Newman took off from Presque Isle, Maine in the gas balloon Double Eagle II and successfully crossed the Atlantic. The flight took 137 hours, 6 minutes and covered 5,021 kilometers (3,120 miles) landing in a wheat field near Miserey, France.

This was the first successful transatlantic crossing by a manned balloon. After Charles Lindbergh’s famous 1927 flight across the Atlantic, ballooning across the ocean remained one of the great, unconquered aviation challenges. Abruzzo and Anderson failed at their first attempt in 1977. Less than a year later with a long-time friend, Newman, the group succeeded.

Extreme temperature variations during the flight caused ice to build up outside the balloon each night, and heat from the sun caused helium to expand during the day. This led to what the pilots called the “Big Drop.” On Aug 6, 1978, Double Eagle II descending to 1,219 meters (4,000 feet) due to atmospheric conditions and then rose to 7,315 meters (24,000) feet the same afternoon after being heated by the sun.
