(CBS/AP) A MD-88 aircraft carrying 43 passengers for Delta Airlines on a Flight from Pittsburgh to Atlanta blew out at least one tire and had an engine fire upon landing Saturday afternoon. At least four passengers sustained minor injuries.

           A Delta spokesperson told CBS News that all passengers aboard flight 2284 were safely evacuated via the rear stairwell, and the fire department sprayed foam to extinguish the fire in the plane's right engine on a runway.

           As of the writing of this report, the plane was still on the tarmac and the incident was under investigation. A spokesman said there was minimal disruption to other flights at Atlanta Hatfield airport, one of the nation's busiest.

          Federal Aviation Administration spokeswoman Kathleen Bergen said the flight from Pittsburgh blew at least one tire as it landed, resulting in the fire.

        Parker said she received a report indicating the problem was caused by "overheated brakes...the plane will be taken out of service and looked at by maintenance."
