Blast From the Past

For those of us of a certain age, this was likely the first video we downloaded on our screeching dial-up modems.

From Wikipedia:

George Thornton, the engineer in charge of the operation, told an interviewer that he was not sure how much dynamite would be needed, saying that he had been chosen to remove the whale because his supervisor had gone hunting. A charge of one-half short ton (450 kg) of dynamite was selected (emphasis mine). A military veteran with explosives training who happened to be in the area warned that the planned twenty cases of dynamite was far too much, and that 20 sticks (8.4 lb or 3.8 kg) would have sufficed, but his advice went unheeded.
