I'm surprised by the majority who don't like fireworks from the air. Maybe it depends on what you like, and where you do it. I've only done it once so far, and found it quite
spectacular. Maybe it's because I was circling about 1000' outside and 700' above tops of the highest bursts along with another locally based 172 that joined us mid-show. I used 70kias with 10 degrees flaps, and once trimmed got to snap pix like
this. If I do it again we might try having some music on the intercom. I turned off strobes and landing lights, since we had flight following and it's very easy to see other traffic at night.
I liked the ability to see them clearly rather than shrouded in thick smoke like is often the case from the ground. Also enjoyed the city lights, reflection in the harbor, seeing where people had pulled cars over to watch in groups on the streets (and even the freeway!), and glimpses of the crowds lit up by the flashes.
By the time we landed a couple of minutes after the show, my wife and I were wearing warm smiles from the relaxation and beauty of it.
I agree with those here and in the other thread who said they liked flying the fireworks, and those who suggested that anyone curious try it yourself. I'm also glad most pilots don't like it, because it would be far less fun with a dozen other planes of various speeds buzzing around the show.
