Bio-Weapons Reactor Prototype
Can all you technical types have really missed the REAL purpose of this experiment? As pointed out, there have been other bio experiments done before. But this time, the environment box is poorly shielded. They hope exposure to cosmic radiation will mutate the flies over several generations.
All those Bond movies missed the boat, China will be the first to have a secret moon base. While Western space agencies languish under budget cuts, the Chinese will develop a race of gigantic space mutant flies. One fine day they will fly to Russia and the United States and begin eating everything in sight. Giant maggots will wallow over the landscape, devouring what the flies don't and crushing everything else. After developing in the harsh conditions on the Moon, they will be tough enough to survive any conventional weapons attack. The West will collapse under the onslaught.
And you thought the little fly was cute...
