“Crossing The Atlantic Feasible” Says Prof. Rotch Of Harvard

CROSSING THE ATLANTIC FEASIBLE SAYS PROF. ROTCH OF HARVARD

“CROSSING THE ATLANTIC FEASIBLE” SAYS PROF. ROTCH OF HARVARD: He Has Charted the Air Lanes Above the Ocean and Future Balloon Voyagers Will Have Their Wind Currents Marked Out For Them. (PDF)

It seems that every week brings another story about air travel, and this one brings good news for those aeronauts planning to cross the Atlantic Ocean in an airship: a Harvard Professor has just completed a study of wind currents that could dramatically cut your travel time.

“It is evident that the currents in the various levels of the atmosphere are of vastly more importance to the aeronaut than are the ocean currents or surface winds to the sailor, since the winds above the earth’s surface blow much faster tan the surface winds, and aerial machines are considerably more bulky than aquatic vehicles of the same carrying capacity.

“Moreover, a balloon or flying machine, wholly immersed in one medium, cannot tack, as a ship floating in the water can advance partly into the wind. Consequently a balloon without motive power can only drift with the current, and a dirigible balloon or flying machine must possess a proper speed superior to that of the current in which it floats in order to make headway against it. Hence the necessity in the case of the balloon without power, and the advisability of the airship or heavier-than-air machine to seek a favorable current in the aerial ocean.”

Problems Of First Transatlantic Balloon Trip

PROBLEMS OF FIRST TRANSATLANTIC BALLOON TRIP

PROBLEMS OF FIRST TRANSATLANTIC BALLOON TRIP: Peculiar Conditions Face the Aeronauts Who Will Attempt to Cross the Ocean in the Dirigible America Under the Auspices of “The New York Times,” the Chicago Record-Herald, and the London Daily Telegraph. (PDF)

By 1910, Walter Wellman had made three unsuccessful attempts to fly an airship to the North Pole when he set his sites instead on crossing the Atlantic. This article describes the ambitious trip and explains how Wellman and his crew will overcome the obstacles they will surely face.

Spoiler alert! They didn’t make it. But they did manage to fly 1,000 miles before needing a rescue. That’s significant because if Wellman had managed to fly 1,000 miles on his earlier expeditions to the North Pole, he would have reached it.

Wellman lived another 24 years, but after this trip he never flew again.
