I am listening to the book Rocket Men by Robert Kurson, and 22 minutes in to the epilogue, the author says the following:
Weeks after the return of Apollo 8, Frank Borman went to work pumping gas at a local Gulf service station in Webster, Texas. He did it for free, along with his two sons, in exchange for use of the station's garage bay and lift where the Bormans could work on their cars.
A cursory Google search does not find any source to back this up. I would like to believe the author did not make this up, is there any source that can confirm this?
The blurb on Audible says that story draws from one on one interviews with the astronauts and their families, but it does not look like these interviews were done by the author himself.
