The Astronaut Farmer.

Texan Charles Farmer left the Air Force as a young man to save the family ranch when his dad died. Like most American ranchers, he owes his bank. Unlike most, he's an astrophysicist with a rocket in his barn - one he's built and wants to take into space. It's his dream. The FBI puts him under surveillance when he tries to buy rocket fuel, and the FAA stalls him when he files a flight plan – but Charles is undeterred.
