The state of Ohio owns two planes and a helicopter, but isn't doing a good enough job keeping track of how they're used or whether the cost of operating them is worth it, a state audit found. The state's two King Air turboprops and its five-seat Eurocopter flew a combined 121.5 hours last year, though the helicopter was rarely used. That prompted the audit to recommend that the state sell the 30-year-old helicopter. And the state should have clear policies on proper use of its aircraft, the audit said. Lawmakers called for an investigation of the state's aircraft usage after two high-level politicians used the planes for private transportation and later reimbursed the state.
