What would they have done if it had rained?

[Charles Drago]

Could the event not have happened?

No, not in my opinion. Unless, by some miracle, we had a Seven Days In May scenerio.
Which only happens in books and films.

We can't speculate but I am positive that they had a back up plan in the (unlikely) case of rain. That involved LHO as too much had been invested in setting him up.

Opps I was responding to CD's question above but in editing out the rest it now looks like it is Jan asking the question. Not sure how that happened.

I won't speak for Jan, but I'm focusing here on the high strangeness aspects of this world-historic case ... the imponderables ... along the lines of, would what for lack of a better term I'll call "fate" have allowed any other assassination scenario to become reality.

Pondering the imponderable ... it's an intoxicating and, for me, thoroughly enjoyable pastime.
