Two planes collide on taxiway in Detroit Airport 

Two planes have collided on the ground at an airport in Detroit. The wing of an American Airlines plane clipped the tail of a Southwest Airlines plane, while both were on the taxiway.  

Passengers had to remain on board the planes but there are no reports of any injuries or fuel leaks. 

The Federal Aviation Authority says it will investigate the incident.  

Some passengers say they saw the planes close to each other, but did not believe they would hit each other until the moment of impact.
