Passage: On Saturday, July 28, 1945, Lieut. Col. William F. Smith Jr. was piloting a B-25 Mitchell bomber on a routine personnel transport mission from Bedford Army Air Field to Newark Airport. Smith asked for clearance to land, but he was advised of zero visibility. Proceeding anyway, he became disoriented by the fog and started turning right instead of left after passing the Chrysler Building.At 9:40 a.m., the aircraft crashed into the north side of the Empire State Building, between the 78th and 80th floors, carving an 18-by-20-foot (5.5 m × 6.1 m) hole in the building where the offices of the National Catholic Welfare Council were located. One engine shot through the South side opposite the impact and flew as far as the next block, dropping 900 feet (270 m) and landing on the roof of a nearby building and starting a fire that destroyed a penthouse art studio. The other engine and part of the landing gear plummeted down an elevator shaft. The resulting fire was extinguished in 40 minutes.

The remains of Navy hitchhiker Albert Perna were not found until two days later, when search crews discovered that his body had gone through an elevator shaft and fallen to the bottom. The other two crewmen were burned beyond recognition. Elevator operator Betty Lou Oliver was injured when the cables supporting her elevator sheared and the elevator fell 75 stories, ending up in the basement. Oliver survived the fall, and rescuers found her amongst the rubble. This still stands as the Guinness World Record for the longest survived elevator fall.Despite the damage and loss of life, the building was open for business on many floors on the following Monday. The crash spurred the passage of the long-pending Federal Tort Claims Act of 1946, as...
