The more information that is released, the more Mr Armstrong looks like a foolhardy idiot instead of a hero.
He was grounded for a suspected 'mini-stroke' or Transient Ischaemic Attack (TIA) which is often a pre-cursor to a full blown stroke - you wouldn't want to be a in a car if the driver was likely to have one so why on earth would you want to be a pax in a helicopter???
I wonder if he mentioned his actual medical condition before risking the lives, not once but 3 times, of the police and medical teams.
One delivery of a 2-man medical team would have allowed the casualty to be stabilised and assessed and protected until daybreak would have allowed a SAR aircraft to complete the recovery.
All this HERO BS is exactly that and, whilst I cannot fault his flying skills, I find his cavalier attitude to his personal safety and that of the rescue teams worthy of any sanction the CAA might impose.
