DFW Airport is located in Grapevine, Texas, and is the headquarters for American Airlines. We were driving down one of the main streets in Grapevine and saw a sculpture on the corner, so we stopped to take a look. It is the Grapevine 9-11 Memorial. Two American Airlines flights – 11 and 77 – were hijacked (and United flights 93 and 175) on 9-11 and used in the attack. This memorial remembers the flight crews from all four flights, as well as the first responders, the police and firefighters. It is quite a stunning memorial.
