I am not talking about curved meteors or those completely changing directions.
Curved meteors are a different story.
The problem with this is that a meteoroid cannot survive the slightest change in directions, due to the extreme velocity it travels as it burns in the atmosphere. For some unexplained reason, I have observed this effect subtly on a small number of meteors, but only one was very obvious. It is still fresh in my mind. In July 1994, while observing in the late evening from my backyard, a magnitude -2 slow speed sporadic in the northeast caught my eye. It was a long persistent 30 degrees path, lasting a few seconds.
