Originally a public domain film from the US Navy, slightly cropped to remove uneven edges, with the aspect ratio corrected, and one-pass brightness-contrast-color correction & mild video noise reduction applied.
The soundtrack was also processed with volume normalization, noise reduction, clipping reduction, and/or equalization (the resulting sound, though not perfect, is far less noisy than the original).

The Curtiss SB2C Helldiver was a carrier-based dive bomber aircraft produced for the United States Navy during World War II. It supplemented the Douglas SBD Dauntless in US Navy service. The SB2C was much faster than the SBD it replaced. A few examples are extant.
Delays marred its production—by the time the A-25 Shrike variant for the USAAF was deployed in late 1943, the Army Air Forces no longer had a need for a thoroughbred dive bomber. The majority order of the A-25 was transfered to the US Marine Corps. The U.S.Marine Corps (e.g. VMSB-151 AliBaba) flying out of Enjibe Island, Enewetok Atoll conducted bombing missions on bypassed strongpoints.
Poor handling of the aircraft was another factor that hampered its service introductions; both the British Royal Navy and the Royal Australian Air Force cancelled substantial orders.
Crew nicknames for the aircraft included the Big-Tailed Beast or just the derogatory Beast, Two-Cee, and Son-of-a-Bitch 2nd Class (after its designation and partly because of its reputation for having difficult handling characteristics). Neither pilots nor aircraft carrier captains seemed to like it.
The Truman Committee investigated Helldiver production and turned in a scathing report, which eventually led to the beginning of the end for Curtiss. Problems with the Helldiver were eventually ironed out, and in spite of its early problems, the aircraft was flown through the last two years of the Pacific War with a fine combat record.
Nonetheless, the type became the main USN fleet divebomber by late 1944 and provided the carrier dive and attack squadron complements of numerous fleet carriers and light carriers...
The U.S. Navy would not accept the SB2C until 880 modifications to the design and the changes on the production line had been made, delaying the Curtiss Helldiver's combat debut until 11 November 1943 with squadron VB-17 on Bunker Hill, when they attacked the Japanese-held port of Rabaul on the island of New Britain, north of Papua New Guinea. The first version of the SB2C-1 was kept stateside for training, its various development problems leading to only 200 being built. The first deployment model was the SB2C-1C. The SB2C-1 could deploy slats mechanically linked with landing gear actuators, that extended from the outer third of the wing leading edge to aid lateral control at low speeds. The early prognosis of the "Beast" was unfavourable; it was strongly disliked by aircrews due to its size, weight, and reduced range compared to the SBD it replaced...
Among its major faults, the Helldiver was underpowered, had a shorter range than the SBD, was equipped with an unreliable electrical system, and was often poorly manufactured. The Curtiss-Electric propeller and the complex hydraulic system had frequent maintenance problems. One of the faults remaining with the aircraft through its operational life was poor longitudinal stability, resulting from a fuselage that was too short due to the necessity of fitting onto aircraft carrier elevators. The Helldiver's aileron response was also poor and handling suffered greatly under 90 kn (100 mph; 170 km/h) airspeed; since the speed of approach to land on a carrier was supposed to be 85 kn (98 mph; 157 km/h), this proved problematic. The 880 changes demanded by the Navy and modification of the aircraft to its combat role resulted in a 42% weight increase, explaining much of the problem...
