Nothing at DFW but I can sure find out for sure. I know some ATP pilots..I'll ask. I monitor tracon quite a bit as they're on approach to final and never heard anything unusual. Maybe I should switch to tower more often..
The usual suspects who think these are kids playing with office depot hand held pointers are either ignorant or plain stupid. [same ones who think open borders are great just because the almighty bush says so]
Thanks very much Indie.
