BNA is nowhere near capacity. Why would we need an alternative?
I'm not sure if there has ever been commercial service to this airport. Corporate Airlines has its headquarters in Smyrna, but has no scheduled service there. However, they do offer numerous charter services.
Lying around the field are old airliners from legacies such as TWA and Pan Am, as well as some NW
727's. This was also a military airfield at one time - although I don't really know any details on the operations.
Nissan Motors assembly plant is located very close to the airport - just beyond the approach end to runway 32.
I do know that there have been several mishaps involving aircraft destined to BNA
mistakenly identifying MQY
's main runway, 14/32 is almost directly lined-up with BNA
's longest runway 13/31. Not sure if an aircraft has actually landed, but there have been several reports of very low-flying airliners over the Smyrna area in years past listed in the local papers.
Mostly, the airport is used for general aviation/flight training and charter operations. There is a control towers that operates during daylight hours and there is an ILS approach to runway 32.
Hopefully someone else can fill in the gaps I've missed or correct me on anything I got wrong!
