That damn heli god that sends down interference to your spektrum signal and jack hammer your heli I to the ground!!!!!!

We went to a new spot today and my buddy went to take off and while spooling up to take off his swasplate started jumping up and down . Sso we whut it down checked it out..we found no issues..so he flew ..landed and I took off and was dping a Barrell roll and all tje sudden I blad bogged realy bad and rolled it back upright and the pitch started pumping up and down ..I started figjting it and try to come back to land .and the pitch sucked me down before I could throw the throttle hold on...and it pile drived in..after it piled in and we determine the cause was signal interference.we noticed our phones where jumping im and
Oit of signal at a rapid pave
..when we left I couldnt send or receive any text or phone calls ..I jad to rebootu phone..tjen we noti e tje mountain was surrounded by ups , fed ex , &other trucking companies that would be using high frequancy cb to contact there drivers

so what do you guys think of this issue..anything you have seen before..any ideas of any other thimgs that may have caused this crash..very curious
