List of accidents and incidents involving the Curtiss C-46 Commando

The Curtiss C-46 Commando was a transport aircraft originally derived from a commercial high-altitude airliner design. It was instead used as a military transport during World War II by the United States Army Air Forces as well as the U.S. Navy/Marine Corps under the designation R5C. Known to the men who flew them as "The Whale," or the "Curtiss Calamity," the C-46 served a similar role as its counterpart, the Douglas C-47 Skytrain, but was not as extensively produced.

After World War II, a few surplus C-46 aircraft were briefly used in their original role as passenger airliners, but the glut of surplus C-47s dominated the marketplace with the C-46 soon relegated to primarily cargo duty. The type continued in U.S. Air Force service in a secondary role until 1968. However, the C-46 continues in operation as a rugged cargo transport for Arctic and remote locations with its service life extended into the 21st century.

Accidents and incidents
Like every other major type in long service and operation, accidents and incidents have been recorded that have substantially reduced the numbers flying. The following list is typical of such a record of operational use.
