This landmark is a great place to visit, offering a unique glimpse into the history of the airbase. The quality of the structure is impressive, with its Duncan Tower Historical Control Tower being a notable feature. The working hours are convenient, with the site being open 24/7. However, there seems to be a lack of innovative features or activities. Overall, it's a must-see for history buffs and those interested in military aviation. The location is easily accessible and the view of the surrounding area is quite nice. Visitors can take a self-guided tour of the facility, which is well-maintained. The site is also well-marked, making it easy to navigate. One thing to note is that the facility can get crowded at times, especially during peak hours. The website provides some general information about the site, but it could be more comprehensive. The nearby Joint Base San Antonio Lackland Street adds to the ambiance of the area.
