The Gospel Blimp went through multiple printings and was turned into a movie to be shown in churches.
The blimp idea was born when a little cluster of friends from a conservative evangelical church enjoying a barbecue in George and Ethel’s back yard began discussing their next-door neighbors. Those folks clearly were unsaved since they were drinking beer and playing cards. Someone who knew them pointed out that they attend a liberal church, but only a few times a year. As a plane went by overhead, a fellow named Herm remarked that if that aircraft had been carrying a message such as “Believe on the Lord Jesus Christ and thou shalt be saved,” the lost neighbors would have received a witness since they also had glanced in its direction.
One thing led to another and the idea was birthed to buy a blimp and have it trail Scripture messages across the sky for citizens to read. They formed a non-profit, got themselves chartered, organized a board with officers, and made Herm, the fellow with the idea, its executive. Soon, Herm resigned his job and went full-time with International Gospel Blimps, Inc.
