If not, from a shorter and confined area surrounded by high obstacles (such as Leicester City ground), it can't be flown because the required obstacle clearance or stopping distance can't be guaranteed and a landing following any loss of power would almost certainly end up in the stands.
I understand what you are saying. The linked S61 video shows a large helicopter in a large (ish) space with a clear reject area, so scale it down to a smaller helicopter in a smaller space and a smaller reject area. Risk flaring into the stands in 15 seconds of exposure v spinning out of control at 400 feet with no airspeed and 30 seconds + of exposure?
