An Idaho man slapped a 19-month-old crying toddler during a flight to Atlanta and told his mother to “shut that n----r baby up,” according to court papers.

Joe Hundley, 60, was charged with federal assault and could face up to one year in prison, according to an FBI affidavit.

Hundley, president of Unitech Composites and Structures, an aircraft parts manufacturer in Idaho, apparently could not deal with the baby’s whimpers as a Delta Airlines flight descended in Atlanta Feb. 8, reported The Smoking Gun.

Jessica Bennett, 33, the boy’s mother, said they boarded the plane in her home city of Minneapolis.

She said Hundley “reeked of alcohol,” was “stumbling around wasted” and drank multiple double vodkas during the flight.

She suspects he was drunk before boarding the airplane.

Hundley claimed he merely asked Bennett to silence the child and drank a single alcoholic beverage.

In a statement provided to KARE-TV, Bennett said that her son is now apprehensive of strangers and that the family has a lot of questions how Hundley could get so out of control. She also said the situation has caused emotional trauma to the entire family.

Hundley plans to plead not guilty to the assault charge, his lawyer said.
