> Cluster Balloonist Abandons Attempt To Cross The Atlantic
> Jonathan Trappe Was Unable To Control The Balloons' Altitude
> Jonathan Trappe's dream of floating across the Atlantic Ocean beneath
> of cluster of helium balloons has ended in a safe landing, but on the
> wrong side of the ocean. Trappe landed his cluster balloon in a remote
> area of Newfoundland at approximately 1830 EDT Thursday, September 12,
> 2013. Trappe had launched at about 0800 EDT from Caribou, Maine and
> had been airborne for only about 12 hours on a 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.
