(CNN) - Do airline passengers have the right to recline?
That simmering debate among fliers escalated Sunday aboard a United Airlines flight that was diverted after two passengers argued over the use of a device that blocks reclining.
A Knee Defender, a gadget that "helps you stop reclining seats on airplanes so your knees won't have to," was at the root of the disturbance.
United Flight 1462 from Newark to Denver was forced to divert to Chicago's O'Hare airport, according to United Airlines. The airline said that it does not allow the use of the recline-blocking device on its aircraft.
A federal law enforcement source, speaking on background, said the incident involved a male and a female passenger, both 48 years old.
Just three ago, a teenager hitched a ride to Hawaii by hiding in the landing gear of a passenger jet. Remarkably, he survived.

No survivors were found, according to Burkina Faso Gen. Gilbert Diendere.
Flight 5017 was carrying at least 116 people when it departed for Algeria. It disappeared from radar after diverting from its planned course due to bad weather, French Foreign Minister Laurent Fabius told reporters.
At least 50 of the passengers aboard the MD-83 were French. Mali will lead the investigation into the crash.
French forces, including two fighter jets, helped search for the aircraft, along with Algerian and U.N. personnel in the region, Fabius said.
Two more fighter jets were shot down over Ukraine Wednesday, less than a week after a passenger plane was shot out of the sky killing 298 people.
The incidents raise new questions about the safety of passenger planes in the U.S.
