This was not a military aircraft or crew and obviously in each case a judgement call has to be made at the time, but I think I would feel happier knowing that even if I ended up with a black eye, or took a pasting my pax were not put in grave danger, than having to explain to their relatives or a court why I took off and put their lives in danger cos some idiot decided to hang on to the skids... That said, if half a dozen angry looking armed men are approaching I wouldn't be shutting down for a chat...
