You need military training to get up there
Have you seen that video of military training jumping on top of each other’s shoulders and pulling up their comrades to scale a tall wall? Well, we think that’s the only way you can enter through this forbidden door. Either that, or the higher-ups want to surprise their recruits who exit through the door with a 10-foot fall onto hard soil.
Or maybe the construction crew realized their horrendous mistake and are planning to build a staircase in the future. We certainly hope this isn’t the case because that’s no fun. Since these guys are in the Air Force, we’re guessing they’re just going to fly their way in through the door.
