Friends one question.....
Today @ 21.33 I heard the unique vibration of WDP-4 when 15610 passed through NOQ,but I didnt feel that same vibration(heard only Normal Horns) @ 22.09 when 15484 arrived APDJ with a WDP-4...Whereas My home is at least 6.4 km from the path of 15610 but my home is only 0.7 km from 15484 path...why such variation freinds please help :)
