My FI flies and builds RC planes for a hobby. He's been doing it with his dad since he was ten, is constantly building and rebuilding planes, and drives an hour to a flying field to hang out with his buddies almost every weekend. He also plans to get his full-scale license after he gets out of school. Needless to say, aviation is a big part of his life.
I'd like to include a nod to his hobby, but I'm out of ideas. I originally wanted to do aviation themed STDs, but the only ones i can find are out of our budget, and I think we're skipping STDs anyway. I also have some "remove before flight" undies for the honeymoon, but I'm looking for something for the reception. I also thought about a groom's cake like this one:

But I was hoping you ladies might have some more original ideas.
Something that doesn't involve his fellow rc pilots hovering planes outside the church doors during our getaway "to see which way he would go". (An actual suggestion/plot posed by a couple of his friends...

)
So...ideas?
