passengers are not allowed to carry weapons in the helicopters.
When did you last see anyone as a matter of regular procedure, bodysearch the ADC to the JTF Commander (or the Commander himself for that matter) before he boarded your helicopter?
I have successfully asked for and received the magazines from concealed weapons for safe keeping and politely asked for said weapons to be "cleared" in my presence prior to boarding but have yet to see any Oil Company dispatch or security employee do the same. They are too busy trying to find cigarette lighters or get people to turn off their mobile phones.
I have found Frag grenades/smoke canisters/CS grenades regularly being carried in JTF and Mopol baggage. It seems Nigerian Civil Aviation Regulations are not compulsory JTF reading!
