Carl Robert Disch, a National Bureau of Standards scientist wintering-over at Byrd Station, customarily travelled between the main station complex and the radio noise building performing his scientific studies. He had travelled the route over 25 times so far this season.
At 0915 on 8 May , Disch departed the radio noise building, presumably returning to the main station complex, 7,000 feet south of the radio noise building. A handline runs from the meterorology building at the main station to the ladder at the base of the radio noise building. When, by 1000 hours, Disch had not arrived back at Byrd, a vehicle search party departed the station to search the area of the handline.

About 1130 his trail was picked up leading west of Byrd Station proper. It led to the southwest corner of the skiway, a distance of about 4 miles. At this point, the search party returned to the station to refuel. They returned to the field and spent 3 more hours trying to pick up the trail, but to no avail. Winds of 25 to 30 knots and drifting snow covered the tracks made by Disch and rapidly covered the tracks of the Nodwell, making the safe return of the search party very difficult. They returned to Byrd at 1815 hours.
At 1900, another search party was sent to investigate the area of the supply line, emergency Jamesway, and dump. No tracks were found. At 1950 all able hands were mustered and made a human chain search from the dump area to the end of the skiway.
Flares were fired every half-hour from the aurora tower and flood lights were rigged over the station. Visibility conditions eventually prevented the flares from being useful and they were discontinued.
Another vehicle search party was launched at 1800 hours on 9 May. It covered a 1-mile-wide by 9-mile-long area running south of the skiway. The party found occasional tracks and followed them to about 4 miles south of the station where they disappeared. There was no noticeable shortening of stride in these tracks.
An eight-man search party, equipped with two vehicles,a Jamesway, and sufficient fuel and provisions to last a week, departed the station on at 0740 on 10 May on a southerly track. It searched to about 12 miles south of the station, marking the trail with flags. No tracks were found, however.
On 12 May, they searched the northeast and southeast sectors of old Byrd Station. The visibility was good but darkness severely limited their range of vision. The next 2 days visibility was so poor, due to blowing snow and fog, that no search was possible.
Disch was fully clothed with the customary Antarctic clothing. The temperature during the search was about minus 44 degrees Fahrenheit. The tracks that were found indicated that he did not contact the handline, which started at the ladder of the radio noise building, but headed in a direction directly downwind.
Due to the length of time Disch has been missing in the exposure of the Antarctic winter, he is presumed dead. Memorial services were held by his fellow men in Antarctica and by friends and relatives in his hometown.

On May 8 shortly after 1:00 a.m. at Byrd Station, Carl R. Disch, Ionospheric physicist for the National Bureau of Standards, was reported missing after he left the radio noise building in a severe storm to walk to the main station complex, 7,000 feet away. Disch apparently failed to make contact with the handline between the radio noise installation and Byrd Station, as a search of the vicinity of the radio noise building disclosed footprints, assumed to be his, leading to the southwest endof the runway. Here the tracks were lost because of blowing snow, and it was not until the morning of May 9 that a party could continue tracking. In the meantime the immediate station area, supply line, and dump were investigated. When the tracks were lost a secont time a major search effort, including vehicles, a sled-mounted hut and a supply of food and fuel, proceeded to the point where tracks were last seen and continued southward for 13 miles from the station on the 10th and 11th, making perpendicular sweeps to the east and west, with no success. In the station area the search continued and a party visited the old Byrd Station 6 miles away. Repeated attempts were made to reach the long-wire site eleven miles to the northwest, although this direction was contrary to the direction of the footprints and almost into the wind, making it a highly unlikely one for Disch to have taken.
Throughout this period, there were intermittent storms with winds up to 45 knots and visibility reduced to zero by heavy blowing snow, seasonal darkness, and overcast. At one point the temperature dropped to -79°F, seriously interfering with the movement of men and vehicles. The station complement utilized the brief twilight at midday and the light of the full moon whenever possible to advance the search efforts.
A memorial service for Carl Disch was held in his hometown of Monroe, Wisconsin on May 14, attended by Dr. T. O. Jones, Head of the Office of Polar Programs, and Mr. Stephen Barnes from the Central Radio Propagation Laboratory, National Bureau of Standards. Further search is planed for the return of daylight in the spring.
