The airport scene was filmed in the San José, California airport.
The USAF plane near the end of the movie is a C-5A Galaxy from Travis AFB, CA. Sadly, it has been sent to the "boneyard" at Davis-Monthan AFB, AZ and is no longer in service.
Vera was actually named Tai (born November 4, 1968), a celebrity Asian elephant best known for playing Bo Tat in the film Operation Dumbo Drop (1995), Vera in Larger than Life (1996) and Rosie in Water for Elephants (2011). Tai was owned by Have Trunk Will Travel, Inc., a privately funded organization that generates income through elephant rides, shows and events, as well as film and commercial appearances.
In 1995, Disney came out with a similar movie plot about an elephant which needed to be transported called "Operation Dumbo Drop"(1995). The characters in that movie also ran into many different problems while trying to transport that elephant across South Vietnam. "Larger than Life"(1996) came out one year after that movie. Both films used the same elephant.
Tracey Walter and Pat Hingle both appeared in Batman(1989)
