The generous donation was made by Normand Bureau, who's spent the better part of his retirement making model airplanes a hobby.
"I had bought one model and it wasn't that hard to do so every time a new one would come out I'd go buy it," said Bureau.
Bureau was moving out of his Lewiston home and realized his planes would need a new place to be appreciated.
"He had no place to store them," said son Thomas Bureau. "We were fortunate that the Maine Air Museum was willing to take on display them here."
The planes displayed are from the World War II and Cold War era.
"He focused on detail, a lot of detail," said Bureau's son. "Especially when it comes to the painting and the characteristics of the plane."
His choice to build military planes makes sense given his background as a Korean War Veteran. He also holds the legendary status as a Maine State Trooper, which is the highest award a trooper can receive.
His son and grandsons chose to follow in his footsteps as well, and were there to see the display on Saturday.
"So it was a good life, a good part of my life, and I'm proud of what I did and I'm glad I brought them here," said Bureau.
