And what country can preserve its liberties if their rulers are not warned from time to time that their people preserve the spirit of resistance? Let them take arms. The remedy is to set them right as to facts, pardon and pacify them. What signify a few lives lost in a century or two? The tree of liberty must be refreshed from time to time with the blood of patriots and tyrants.
In June 1982, Columbia Helicopters was hired by Sohio to participate in a test on Alaska's North Slope. The purpose of this test was to evaluate the ability of a helicopter - the Boeing Vertol 107-II - to tow a fully-loaded hover barge over water, snow and ice.
The test began in Prudhoe Bay on June 17. The Vertol's 600-foot long line was connected to hover barge ACT-100, jointly owned by Global Marine Development and VECO. Air blowers on the 170-ton barge forced a cushion of air under the barge, which was kept in place by rubberized skirt material.
This first test was run around Prudhoe Bay with an empty barge, and was successful. During this and subsequent tests, the aircraft often flew with a nose-down angle approaching 25 degrees. Next, ACT-100 was loaded with 40 tons of cargo for another close-in test run. Once more, the helicopter showed it could move the barge despite the additional weight. The final aspect of the test was to tow the hover barge over a 50-mile course to a drill site named Alaska Island where Sohio had just completed an oil well.
During the tow to the island, headwinds over 30 knots were encountered, and snow and ice buildup were also factors. Regardless, the Vertol was able to bring the empty barge to the island successfully. On the return trip to Prudhoe Bay, when this photo was taken, the barge carried 50 tons of cargo, bringing the total weight to 220 tons. As with the previous tests, this task was accomplished successfully.
This photograph is one of longtime Columbia Helicopters' photographer Ted Veal's most famous photographs. The use of a powerful telephoto lens makes it appear as though the helicopter is closer to the ice than is actually the case.

Thanks for that.
DeleteWow, thanks for filling in the story, Brigid! You weren't, perchance, piloting that chopper, were you?
DeleteVery interesting.
ReplyDeleteThere's a pilot who clanks when he walks.
ReplyDeleteAmazing. Just amazing. Thanks for the background, Brigid.
