The videos don’t show what the aircraft is doing, but in most cases the plasma track is visible for several seconds.

One of them that was shown on the local news showed a plasma track that had to be 1500 feet tall, and the idiots called it a “fire tornado.” (Tornados are cold core phenomina.)

This? https://abc7chicago.com/video-firenado-whips-around-camp-fire-in-california/4654324/ It has flames shooting upward. It is not a red laser or any kind of visible beam weapon. I suppose there could be an nonvisible beam in there and the flames could follow it, but that is completely speculative.

Is the plasma track visible for "several seconds", not 30? How many seconds? If you want to start a fire, then one or a few seconds is perfectly adequate with the output from a kW scale power source. But if you want to melt metal you need MW power, or lots of time on target. Melted metal is not evidence of beam weapons,. The firenado is not evidence either, it is simply a fire whirl, well understood for decades: https://scholar.google.com/scholar?cluster=13095096689738521867&hl=en&as_sdt=0,47
