Strikes me there is a lot of unrelated traffic in the immediate area and more importantly on the assigned frequency ( shared by multiple heliports, 2 airfields, one of which offers training, and a popular low level scenic route for pros and weekend warriors alike). It would be all too easy for the typically brief company broadcast to get trodden on or swamped in the noise of sunny, public holiday traffic. Throw in an approach from an unexpected direction or an early return to the pad and the first few holes of lost situational awareness can start lining up. 😥
I don't indulge in the rotary vice, but am often airborne and waterborne in the vicinity and have never witnessed anything which struck me as remotely cowboyish or unsafe about the operation. In any event, a tragedy for all concerned, let's hope all those still in hospital make a full recovery.
