Interesting choice of "when" not "if" in the title. Very optimistic.

I do wonder if they've figured out what those tic tac style UFOs are that keep getting reported over in the Americas off the coast though.

Research and preperation like this could perhaps be based off of how we make contact with others in general that don't have our language - but i wonder if body language and motioning to things would really even help, if those things happen to also (pardon the pun) be alien to them.

Interesting topic to think about!
