Several points in a story on Sunday’s F1 about Silver Wings Aviation need clarification. Among them: the 20 percent to 30 percent boost anticipated by the air service’s fuel sales were to the fuel-sales revenues, not the overall revenue. The airport’s overall receipts last year were $400,000. Also, the stated figure of 450 companies that have used the Auburn-Lewiston Municipal Airport is only an estimate based on invoiced landing fees. And the number 71,000 represents operations such as takeoffs and landings, not necessarily pilots.
