History of the Flight
United's Trip 12 of April 10, 1942, originated at San Francisco, California, with New York, New York, as its destination. Intermediate stops were scheduled for Oakland and Sacramento, California; Reno, Nevada; Salt Lake City, Utah; Denver, Colorado; Omaha, Nebraska; Chicago, Illinois; and Cleveland, Ohio. It was scheduled to depart from Cleveland at 2:55 a.m. (EWT) April 11, but departure was delayed until 3:38 a.m., awaiting the arrival and landing of air express shipments.
The flight to Cleveland was reported to have been routine. Some doubt was felt at Cleveland as to weather minimums enroute, but after the cargo delay at this point, further concern was removed because of improved conditions and the trip proceeded to La Guardia Field with weather at New York reported as 600 feet and 8 miles with conditions still improving. After leaving Cleveland, the flight was reported as on top at 11,000 feet in Sunbury, Pennsylvania, descending to 9,000 feet at Allentown, Pennsylvania.
