Five airline crew have been hospitalised as a precaution due to noticing a mysterious odour whilst departing from Philadelphia to Fort Lauderdale in Florida.

After the plane landed in Florida at around 11am PST, American Airlines confirmed to Fox News about the incident.

“Shortly before landing, crew members complained of an odour on board,” a spokeswoman for the carrier told Fox News

“The aircraft, an Airbus 320 with 137 passengers and a crew of five, landed safely and taxied to the gate. Two pilots and three flight attendants asked to be taken to the hospital as a precaution.

“No passengers requested medical attention. The aircraft is being evaluated by our maintenance team.” 

No word has been received as to whether or not the crew members are in good health.

According to a witness, they wouldn’t let anyone else board the plane.

“I heard one of the security guys walk by, and he's like, 'I need four wheelchairs. We need one ASAP,” passenger Andrew O'Donnell told ABC 10, according to

“They just sort of wheeled everybody off and they said they smelled an odour on the plane.

“And when that happened, they said that they obviously weren't going to let anybody else on.”
