In the new twisters movie which i saw in theaters the day i posted this theres 2 scenes with tornado sirens which weird me out, in the rodeo scene there is a visible ASC T-121 and instead of sounding like it usually does

the creators of the movie decided to play the alert tone of a whelen vortex R4
Same thing with a shot in the movie when the tornado is striking el reno there is a 2t22 that is in the scene and instead of playing its regular tones

Another strange thing is when the ASC T-121 got ripped off its pole it was still sounding even though its power supply had been completely cut
