I find it hard to believe that on this forum, a "Professional Pilots'" forum after all, that such a question can be asked and attract such a slew of rubbish, illegal, utterly unprofessional and downright dangerous suggestions, surmise and guesswork on such a serious subject.
Is there truly no Professional here who can quote the rules regarding hanging extraneous bits off a helicopter as opposed to surmising about what they might want to, hope they could do, think they ought to be able to do, hope they could get away with or have decided is safe simply because it suits them to say so?
Professional? For shame.
