Wings Over Dallas delighted attendees with rare World War II-era planes, aviation education and family activities.
The show also annoys some neighbors near the Dallas Executive Airport, where noisy old planes were flying overhead all weekend.
But one neighbor found a part of the show in his own front yard.
A Kiest Park-area neighbor found this hunk of metal near his curb. A friend who is a pilot said it looks like engine cowling.
Neighbors contacted the Commemorative Air Force, which is housed at the old Red Bird airport, and they came and picked it up.
