Did The Lost Soviet Flyers
Fly Into Our Hollow Earth?

Vilhjalmur Stefansson, in his book, Unsolved Mysteries of the Arctic, explains how on August 12, 1937, a four-engine aircraft of passenger type left Moscow, bound for Fairbanks, Alaska via the North Pole with a crew of six seasoned flyers, were lost and never found even after a year of diligent search.

Most likely, the Lost Soviet Flyers flew into our hollow earth by accident. 

Stefansson wrote in his book, that the Soviet Flyers encountered a stronger wind as they approached the pole than the forecasts had led them to believe.  They reported that at 20,000 feet the wind was about 62 miles an hour and was cutting almost that many miles from their speed because it was nearly straight against them.

Stefansson reported that everything continued well for nearly two hours after they crossed the pole and that they were moving down upon Alaska on the Fairbanks meridian.  Then came the only distress message, that they had been forced to descend from 20,000 feet where they had been flying in bright sun shine to the 13,000 foot level because one of the four motors had gone dead from an oil line damage.  The last words heard were, "Do you hear me?"  and "We are landing in..."  Unintelligible messages were received over the next several days, but became gradually weaker until they finally died out.

Subsequent rescue missions were flown both from the Soviet side and the Canadian and Alaskan side of the Arctic over the next year looking for the downed Soviet Flyers but they were never found.

After reviewing all the downed Arctic fliers that had ever been known to come down in the Arctic, Stefansson concluded that the Soviet Flyers were the only ones that had ever been lost in the Arctic.  The Americans alone flew about 40,000 miles in search of the Lost Soviet Flyers over a period of about one year covering the Arctic on the Canadian side of the pole down into Alaska.  See a National Geographic map of those search flights here.  Russian search flights flew up to the pole, but did not cross over.  Most likely, had they retraced the exact path taken by the Lost Soviet Flyers, they, too, would have been lost and gone inside the earth through the north polar opening.

As reported by Retired Colonel Billie Faye Woodard, the North Polar Opening is located at 87.7 N Lat, 142.2 E Lon.  Therefore, as the Lost Soviet Flyers flew up from the Kara Sea towards the North Geographic Pole, they would have reached a point on the lip of the polar opening where their sextant reading of having reached the pole would have deceived them into believing they had actually arrived there sooner than they expected.  This may be why they reported a stronger head wind than their weather forecasters had predicted thinking it was slowing them down, when in reality what happened was that they arrived sooner to their sextant determined pole than they had expected and attributed it to a strong head wind.  Then at their sextant determined pole, which really was not the geographic pole at all, but a point on the curvature of the polar opening that gave the same sextant reading showing the sun to be the correct distance above the horizon as if they had reached the north pole, they then made a turn to the right towards Alaska on what they thought was the Fairbanks meridian, but which instead took them directly through the neck of the polar opening and into our hollow earth.  See a map of their trajectory into the polar opening here.  After about two hours they would have reached the inner continent and so decided to descend to see what they had found.  From that point on, their radio signals were received in gradually weaker form as they descended further into the interior of the earth.
