Former business partners said Richard Heene wanted a show of his own called "The Science Detectives" or "The Psyience (sic) Detectives".
The saga gripped a global audience, first with fear for the safety of 6-year-old Falcon Heene and then with anger at his parents when he was discovered.
Eleven years later, couple has now "paid the price in the eyes of the public" and shouldn't have to be dragged down by a criminal record for the rest of their lives, Colorado Gov. Jared Polis said in a statement Wednesday.
"We are all ready to move past the spectacle from a decade ago," said Polis, a first-term Democrat.
Richard Heene served a month in jail after pleading guilty to a felony count of attempting to influence a public servant, and Mayumi Heene was jailed for 20 days for filing a false report. They were also ordered to pay US$36,000 in restitution.
The couple told ABC News last year that it wasn't a hoax because they truly feared their son could have been aboard the balloon when they called for help.
Polis also issued 16 other pardons and four commutations.
