I once gave a presentation at which I explained why we had chosen the MD902 for the London HEMS role. Afterwards the EC(F) rep cornered me and asked why I thought the NOTAR a better bet than the fenestron. I explained that in the crowded streets of London the fenestron still represented a theoretical threat and the NOTAR did not. Why should I take that (small) risk? He didn't answer but disappeared into the audience with a large 'thought' bubble over his head.
In the end it's all about risk management and I don't believe we should take one extra risk if we don't have to.
