Excerpt from letter of Nautilus crewman James Irvin
"Just a line to let you knew we are making history again for the first time. We are supposed to pass over the North Pole sometime tomorrow night. So far, all has gone real smooth .. . no trouble at all on this trip. I just hope all goes well the next five days . . . then we will be out from under the ice again. We have known ever since we left Seattle where we were going but no one could tell . . . top secret information.
