To be fair most of the Mossies used in the film were destined for the scrap heap anyway. The film probably saved a couple for posterity.
It's like experiments on animals. It is for the greater good, but it does make the hairs on my back stand looking at the poor monkey in the cage, about to give his life for science.
Today, when flying mossies are extinct, it is a difficult thing to watch a real one burn.
Are there any Beau's in flying condition?
