A close look at an A-1 Skyraider's damaged propeller blade, bent upward from a ground strike, illustrates the hard-won wear these aircraft endured through hundreds of combat missions. In the background, sister aircraft "Redtag 66 Express" waits on the ramp. This photograph comes from the Don Engebretsen collection, documenting 200 A-1 Skyraider combat missions flown during the Vietnam War. Project: 218822
