Something Stinky Made BUR-Bound Flight Go Back to OAK

It was an unintentional round-trip for passengers aboard a Southwest Airlines flight headed to Burbank's Bob Hope Airport (BUR) from Oakland (OAK), and if you ask the passengers, something about this trip really stank. Literally.
Passengers in the cabin reported "a strong odor" on Flight 508, which took off at about 7 a.m. and circled right on back to the airport about 20 minutes later, reports SFist.
No description of the odor has been made available, however we do know that it made one flight attendant ill. That flight attendant was able to walk off the plane on her own and was hospitalized. All of the passengers deplaned, and were transferred to another flight, said Southwest spokesman Brad Hawkins, according to L.A. Now.
The aircraft will be inspected to figure out the cause of the powerful plan-changing odor.
