Narrative:

We were doing a fly-by of the south shore of the lake, northeast of ZZZ, us, for an association of veterans who were having their annual get-together. They had contracted with us to do a fly-by for their crowd as our airplane is configured like the aircraft of the era. The guns are, of course, fakes. I think the park where the get-together was held was okay with our show, but I didn't actually talk to them myself. The veterans association simply told me that they were ok with it. All proper altitudes were maintained. There are so many different auths and agencies involved with anything that is done anymore that there is always somebody, you either forget to check with, or that you just don't know about.
