Theme for 60th Anniversary party for a Business

This is what Hill Aircraft was looking for in their graphic design

We are looking for a theme for our 60th year party. The theme we used for our 50th party was a movie premier with a drive-in movie. Info on our 50th party is here http://hillaircraft.com/about/50th-anniversary/. The theme must incorporate what we do as a business. Full website at www.hillaircraft.com. The theme would be expanded upon with the use of props or other items to make a large celebration. The party would have around 400 invited guests to take place at our business location on an airport. Please provide details of your theme along with potential props, activities, or other items that would make your theme work. A logo for the theme will also be needed and could be provided with the theme. Read more
