London: A video from an Apache helicopter`s on-board camera that was leaked online shows a US pilot blowing up an Afghan man while singing "Bye, bye Miss American pie".
As the pilot launches a missile at a group of people in a street, he is seen humming the famous tune from the 1971 album by Don McLean, The Sun reported.
The caption on the video leaked on website Liveleak.com claimed the people on the ground were "innocent farmers planting poppyseed".
The weapon used on them was claimed to be a one kg Hellfire missile.
After the Afghan man is killed in the massive explosion, the co-pilot can be heard saying "Nice".
The pilots then fire a machine gun at two other people.
A disgusted user of the website left a comment: "It`s disturbing and bordering on sanctioned psychopathy to enjoy killing so much".
