Yeah, unfortunately they took their downloads down.
UFO_0.98d is the latest version I can find, and I do have it from before the downloads were taken down, so anyone who wants it should send me a private message and I will e-mail it to you.
I have to admit I sort of forgot the calculation myself. 3 shots at 40% would be… 40% x 1.4 x 1.4 ~ 78% chance that at least one shot hits?
