This F-15 was the first fighter to answer the call as two airliners under the control of terrorists headed towards the World Trade Center on Sept. 11, 2001. It was discovered by the Pacific Coast Air Museum located in Santa Rosa, Calif., just before it was to be destroyed. Museum board member Craig Schulz aided in purchasing the aircraft and getting it to Santa Rosa’s Charles M. Schulz–Sonoma County Airport where visitors can view it. Museum officials said the pilot was cleared to use guns to bring the airliners down but couldn’t get to them in time. This was taken on Monday June 24, 2013.
