Near the gates of the National Security Agency at Fort Meade, Maryland, a C-130 Hercules sits in National Vigilance Park, on a small sliver of land sandwiched between a gas station and a parking lot. The aircraft is painted to represent Air Force 60528, which was shot down by four MiG-17s on September 2, 1958, after entering Soviet airspace. On the NSA website, a grainy gun-camera image from one of the MiGs shows the C-130 ablaze; it crashed 28 miles inside the Armenian border, and all 17 crew members were killed.
