Mobile Lounge action at the 2023 Dulles Day Festival (part 3)

These mobile lounges are now over 60 years old and are due to be overhauled in the next few years, so I got an exterior video of them at the Dulles Day festival since this was the best chance for me to see them in person outside of the terminal on the airfield as well as that there are hardly other videos like these on KZbin.
