I'd say those people were shooting to get attention of the pilots.
When I was young, I was taught to shoot three times in the air if you
needed help.

I don't know how you would know people were shooting at you. Even in
wartime the only way you know is by looking at the tracer bullets or
little flashes on the ground. I suppose if someone actually hit your
aircraft you would notice, and you might receive reports from people on
the ground.

When I was young, I was taught all sorts of crazy things, too. I
probably still believe some of them, but I have learned to try to be
skeptical of them.
