I think you will find that many insurance companies will not insure 'high profile' individuals (so called celebs etc) to fly in singles any more. They want twin engine, two crew machines. I know of one particular instance, quite a few years ago, when Sly Stallone arrived at Battersea and walked up to 'his' B222 with only one pilot, then promptly about-turned and refused to get in. His comment: his insurance company would only allow him to fly twin crew in a twin engined helicopter! He's not the only one, either.
