>> flight that was expected to take 3-6 days.
>> ANN spoke to Kevin Knapp, a veteran gas pilot, who had the first duty 
>> shift in Trappe's control center following the launch. According to 
>> Knapp, the cluster balloon was never able to achieve a stable float 
>> altitude and developed a severe yo-yo effect --- rapid descents with 
>> the aircraft hitting the surface of the water, followed by rapid 
>> ascents to altitudes as high as 21,000 feet or more. Trappe was 
>> unable to gain a steady hand on the errant balloon cluster, which at 
>> 3,000 cubic meters of volume, was the largest in the world.
>> Flight service expressed real concern over the inability to control 
>> the aircraft as they watched it repeatedly descend below their radar 
>> and then reappear climbing rapidly. Trappe and his team obviously had 
>> the same concern and with Newfoundland representing 'land's end' 
>> before venturing out over the Atlantic, the decision was made to 
>> terminate the attempt.
>> Knapp tells ANN that Trappe was able to execute a landing after 
>> darkness had fallen and in low visibility. In fact, he says Trappe is 
>> uncertain if he is on the ground or possibly in trees, but he is down 
>> and safe. Trappe noted on his own Facebook page that he planned to 
>> spend the night in his gondola/lifeboat and had lowered the exposure 
>> cover. Knapp said it was raining in the area and storms were expected 
>> overnight, however the weather trajectories for winds aloft showed 
>> that in a perfect world Trappe could have reached Ireland in 94 hours.
>> Trappe posted on his Facebook page about 2000 EDT "Landed safe, at an 
>> alternate location. Remote. I put the exposure canopy up on the boat. 
>> Will stay here for the night."
>> Trappe has already made history as a cluster balloon pilot having 
>> been the first to cross Lake Michigan, the English Channel and the 
>> Alps before making this attempt at the Atlantic.
>> The first crossing of the Atlantic by balloon was accomplished in 
>> 1976 by the late Ben Abruzzo, Maxie Anderson and Larry Newman in 
>> their helium balloon Double Eagle II -- so named because it was the 
>> second attempt by Anderson and Abruzzo. Bertrand Piccard and Brian 
>> Jones required 3 attempts to get the Breitling Orbiter balloon around 
>> the world for the first time, and the late Steve Fossett was not 
>> successful in his solo balloon circumnavigation until his 6th attempt 
>> in the Bud Light Spirit of Freedom.
