Authorities in Argentina released two passengers detained for obscene exhibitionism after they were allegedly caught having sex in the business class cabin of a Copa Airlines flight from Panama.A minor passenger alerted flight attendants to the couple's suspicious behavior at 10,000 meters, prompting airport police to arrest the pair immediately upon landing in Rosario.The Prosecutor's Office is currently processing the case, which legal observers expect will conclude with fines or mandatory community service rather than imprisonment.
