Open houses are 'soft' recruitment tools.
We allow people to walk thru the tankers and cargo jets, all the way up to the cockpit. For smaller jets like the F-16, we do allow sit-ins, especially for the kids. There are exceptions, of course, and for now, the exceptions are the 'stealth' airplanes. They are roped off and guarded. When the SR-71 was active duty, it was a premium treat for any airshow to host an SR-71 because its squadrons were always busy so usually it was a fly-by, seldom static display, and when there was a static display, there were guards around the jet and their rifles were loaded with real ammo. After the SR-71 retired, it was the F-117 that was the star. Today, it is the F-22, F-35, and B-2.
It is hard work to clean up the jets after an open house. The greatest danger is Foreign Object Damage (FOD) because people, especially kids, drops stuff inside the jets. So basically, after the airshow, each airplane is Red X-ed, meaning grounded. Then Maintenance have to do a full inspection before releasing the airplane back to duty. Maintenance also have to do a complete 'FOD Walk' on the flightline to pick up after the public. Everybody in the squadron helps out the post airshow FOD walk. We find anything, from wallets to soda cans and even underwear. The wallets we return to the owners,
the underwear we toss in the trash.
