Actor John Travolta and wife, actress Kelly Preston, share a laugh as they describe the building of their aeronautically-inspired dream house in Florida, during a special Architectural Digest Magazine program at the Museum of Natural History October 5, 2005 in Washington, DC. The program salutes Hollywood celebrities and their personal style and was used not only to showcase the couple's home, but also to promote the upcoming book, "Architectural Digest Hollywood at Home."
