Authorities at Miami International Airport on Wednesday morning detained a man who stowed away in the landing gear of a plane that arrived from the Dominican Republic.

An airline employee noticed the man as he climbed from a wheel of American Airlines flight 680 shortly after it touched down from Santo Domingo, according to the Department of Homeland Security.

The man, whose name or age was not released, was in good condition, having braved below-zero temperatures during the one hour, 40 minutes flight, said Zach Mann, a DHS spokesman.

The stowaway will be repatriated to the Dominican Republic. Federal agents are investigating how he breeched airport security in Santo Domingo.

''This doesn't happen all the time,'' Mann said. "But I've seen it in the past.''
