You know Aircraft Spruce. So do all your flying buddies. Cutting to the chase, if you are involved in airplanes other than airlines and military, you not only know Aircraft Spruce, you’ve probably bought from them.

After a decade mom Flo Irwin started another business at home, featuring a single product: aircraft-grade lumber …hence “Aircraft Spruce.” Spruce …and So Much More Well, supplying wood to build airplanes is ancient history now, you might say. If you said this, you would not be alone but you’d be absolutely wrong.
