It is unclear if anyone else was aboard the plane.Rob VanKammen, 35, a graphic designer who works near the airfield, said he he was walking to his car when he saw the small plane coming in very low before it disappeared out of his view and crashed."It was coming in at a 45-degree angle, sideways," VanKammen said. "The plane goes below my vantage point, and then all I see was the explosion and the smoke and the flames going up in the air," he said.A team from the National Transportation Safety Board is expected to arrive Thursday, McLaughlin said.Timmerman Airport is a smaller, general and private aviation airfield in the northwest part of the city. General Mitchell International Airport is Milwaukee's main airport.
