Officials say the Pullman-Moscow Regional Airport needs improvements to keep up with more demand and bigger aircraft.
Airport Executive Director Tony Bean says the airport has fallen behind the times due to aircraft increasing in size.
Bean says there isn't the space and capacity to land current-size aircraft safely, and as the trend doesn't seem likely to change, the problem will only worsen.
The Moscow-Pullman Daily News reports that the concerns are the driving force behind a $66 million project to realign and extend the runway and move the terminal at the airport.
The project would be funded through a grant from the Federal Aviation Administration, of which the region will be liable for 10 percent.
