Original Item: One-of-a-kind. First issued early in WW2, the Type B-1 Summer Flying Cap saw service in Africa, Europe and the Pacific. It was popular among pilots and ground crew alike, as it was made of breathable fabric, had a slightly longer brim and a more comfortable fit, as it fits lower in the back than most modern baseball caps. The top is made of 4 panels, so it does not need a central "button" like many caps.

This example is in great condition with signs of faithful use. The cap itself features (3) familiar and legible signatures. The cap bears the signatures of the commander and crew members of the Enola Gay.

The Names Present:
- Colonel Paul W. Tibbets Jr. – Pilot and Aircraft Commander
- Captain Theodore "Dutch" Van Kirk – Navigator
- Second Lieutenant Morris R. Jeppson – Assistant Weaponeer

There appears to be another signature but we are unable to decipher what is written, this can be found below Colonel Tibbet’s name.

A lovely, great display item signed by members of the Enola Gay. Comes more than ready for further research and display.

Hiroshima Mission
On 5 August 1945, during preparation for the first atomic mission, Tibbets assumed command of the aircraft and named it after his mother, Enola Gay Tibbets, who, in turn, had been named for the heroine of a novel. When it came to selecting a name for the plane, Tibbets later recalled that:

... my thoughts turned at this point to my courageous red-haired mother, whose quiet confidence had been a source of strength to me since boyhood, and particularly during the soul-searching period when I decided to give up a medical career to become a military pilot. At a time when Dad had thought I had lost my marbles, she had taken my side and said, "I know you will be all right, son."

In the early morning hours, just prior to the 6 August mission, Tibbets had a young Army Air Forces maintenance man, Private Nelson Miller, paint the name just under the pilot's window. Regularly assigned aircraft commander Robert A. Lewis was unhappy to be displaced by Tibbets for this important mission and became furious when he arrived at the aircraft on the morning of 6 August to see it painted with the now-famous nose art.

Hiroshima was the primary target of the first nuclear bombing mission on 6 August, with Kokura and Nagasaki as alternative targets. Enola Gay, piloted by Tibbets, took off from North Field, in the Northern Mariana Islands, about six hours' flight time from Japan, accompanied by two other B-29s, The Great Artiste, carrying instrumentation, and a then-nameless aircraft later called Necessary Evil, commanded by Captain George Marquardt, to take photographs. The director of the Manhattan Project, Major General Leslie R. Groves Jr., wanted the event recorded for posterity, so the takeoff was illuminated by floodlights. When he wanted to taxi, Tibbets leaned out the window to direct the bystanders out of the way. On request, he gave a friendly wave for the cameras.

After leaving Tinian, the three aircraft made their way separately to Iwo Jima, where they rendezvoused at 2,440 meters (8,010 ft) and set course for Japan. The aircraft arrived over the target in clear visibility at 9,855 meters (32,333 ft). Navy Captain William S. "Deak" Parsons of Project Alberta, who was in command of the mission, armed the bomb during the flight to minimize the risks during takeoff. His assistant, Second Lieutenant Morris R. Jeppson, removed the safety devices 30 minutes before reaching the target area.[15]

The release at 08:15 (Hiroshima time) went as planned, and the Little Boy took 53 seconds[16] to fall from the aircraft flying at 31,060 feet (9,470 m) to the predetermined detonation height about 1,968 feet (600 m) above the city. Enola Gay traveled 11.5 mi (18.5 km) before it felt the shock waves from the blast.[17] Although buffeted by the shock, neither Enola Gay nor The Great Artiste was damaged.[18]

The detonation created a blast equivalent to 15 kilotons of TNT (63 TJ). The U-235 weapon was considered very inefficient, with only 1.7% of its fissile material reacting. The radius of total destruction was about one mile (1.6 km), with resulting fires across 4.4 square miles (11 km2). Americans estimated that 4.7 square miles (12 km2) of the city were destroyed. Japanese officials determined that 69% of Hiroshima's buildings were destroyed and another 6–7% damaged. Some 70,000–80,000 people, 30% of the city's population, were killed by the blast and resultant firestorm, and another 70,000 injured. Out of those killed, 20,000 were soldiers and 20,000 were Korean slave laborers.

Enola Gay returned safely to its base on Tinian to great fanfare, touching down at 2:58 pm, after 12 hours 13 minutes. The Great Artiste and Necessary Evil followed at short intervals. Several hundred people, including journalists and photographers, had gathered to watch the planes return. Tibbets was the first to disembark and was presented with the Distinguished Service Cross on the spot.
