Factual error: When the new candidates report in to Rescue Swimmer School, one of the airmen is wearing the Silver Star ribbon. The person is too young to have served in another service, and there are no other service's ribbons worn - and the Coast Guard hasn't issued a Silver Star since Vietnam.
Trivia: During the scene in Kevin Costner's office after the bar brawl involving Ashton Kutcher and his Coast Guard buddy Hodges, the title of the newspaper from which Costner reads about Kutcher's car accident is "The Cedar Rapids Chronicle." Kutcher is actually from Cedar Rapids, Iowa (although the real name of the paper is the Cedar Rapids Gazette).
Trivia: In the final scene when Jake goes back to pick up Emily at school (ala An Officer and a Gentleman), his short-sleeved dress shirt has no pockets, a strangely shaped collar and appears to be unbuttoned far too far. In the original script, Kutcher was wearing a "polo" style shirt and slacks, but the test audiences raised too many questions about his status: "Had he stayed in, gotten out, what?" that the director had a team CGI a nametag, collar devices, ribbons and proper colors to the clothes he was wearing. explaining the lack of pocket, odd collar and button issue. This is all verified on the dvd extras.
