CADDO MILLS, Texas (AP) _ Two small planes collided in the air on Wednesday, killing at least three people.

``I saw two planes, they looked like they were doing some kind of acrobatics, and one of them hit the other one and knocked the wing off,'' witness Clay Bundy. He said the planes ``went straight down.''

Two men aboard a Cessna 182 were killed, as was at least one person aboard a Piper PA28-181, sheriff's Maj. Tommy Deeds said.

He said counting the number of victims was being complicated by the complete destruction of the Piper.

``They haven't recovered a third body. You couldn't even tell it was an aircraft,'' Deeds said.

The planes crashed in a rural area about two miles northwest of Caddo Mills Municipal Airport, which is about 40 miles northeast of Dallas, said a spokeswoman for the Texas Department of Public Safety, Laureen Chernow.

The Federal Aviation Administration and the National Transportation Safety Board were investigating.
