Interesting that Henderson's LinkedIn page has endorsments from a certain charter broker. As a private aviator flying private aircraft not on AOCs, one wonders why he'd have a particular relationship with a charter broker? Charter brokers more than anyone know the rules, at least they should. With a bulging portfolio of contacts from the sports personality world, one wonders how often the odd jocky, golfer or footballer, or their agents, PRs etc. still go through a friendly charter broker but get a cheap, non-AOC deal, off the balance sheet so to speak.
Like estate angents, charter brokers are not regulated, litterally anyone can sell 'charters' from their kitchen. You have charter industry representative bodies like BACA with 'Codes of Conduct' and no doubt members of such organisations are legitimate and behave themselves, but for every 'good guy' there are probably ten 'bad'. Caveat Emptor.
