Founder of Minnesota-based Precision Lens dies when vintage airplane crashes in Montana

The founder of the Minnesota-based medical products company Precision Lens died when a vintage plane crashed shortly after takeoff at an airport in Montana. The aircraft was a World War II vintage P-40E registered with the Federal Aviation Administration to one of Ehlen’s LLCs. “Precision Lens is saddened by the passing earlier today of its founder Paul Ehlen,” the company said in a statement. Precision Lens is based in Bloomington, Minnesota. In February, a federal jury found Ehlen and his Cameron-Ehlen Group Inc., which does business as Precision Lens, violated the federal anti-kickback statute and False Claims Act.
