How many bombs were dropped in Laos by the US Air Force from 1965 to 1973

This video shows the US Air Force bombing campaign in Laos, from 1965 to 1973. The data comes from the website of the National Regulatory Authority of Lao PDR (NRA), which oversees UXO clearance in that country. They received the data from the US Embassy in Vientiane in 2000, from records originally created by the Department of Defense and stored at the National Archives.
The NRA data sets include information on the number and types of aircraft flown, types of bombs dropped, target conditions and after-action reports. For this graphic, only the dates, latitude and longitude, and the number of bombs dropped per mission are used.
The US Air Force began bombing Laos in June 1964. Many branches of the US, Thai, Lao, South Vietnamese and other forces also conducted aerial missions. But this graphic reflects only bombing missions noted in the NRA data, which show US Air Force missions beginning on October 1, 1965.
