What do you know about the so-called Alternative 3 plan?

Question

I have only recently read about it. If one believes it exisits then, obviously, there must have been an Alt 1 and Alt 2 plan as well. Can you explain what, and how, you know of such plans?

Answer 1

Alternative 3 was a hoax carried out on British TV about 30 years ago, You can check it out on Wikipedia.
