Another one of the criticisms of the Pigeon Post I've heard multiple times is the problem of rain and other adverse weather will have on the electronic systems and on the Smart Cases.  

Now I'm not an materials expert or an electrical engineer but looking at this product demo video, I think I might have just found a solution.  Ladies and Gentlemen, I give you NeverWet:

One question I have about this super-hydrophobic wonder spray is how easy is it to remove?  Is there a anti-superhydrophobic cleaning solution?  

So who will be the first to use this stuff on their UAV and test it out in the rain?
