I once spent a day during a general election campaign going round the UK in a helicopter. It was a fascinating experience, but not one I’d like to repeat. Choppers seem to me to be ludicrously primitive machines — a bit like steam-powered automobiles. They are also, of course, vanity toys for the very rich. And they are incredibly noisy. So this Bloomberg video brings a welcome dose of reality to chopper-worship.
