Since when do brokers provide any kind of commitment to the safe ending of the business transaction (i.e. chartering an acft) ? I mean, especially in Europe. In the US you have the various "Golden Squib Award" and the "Triple Platinum Radioactive-free Certificate" that may be used as a guideline for the customer to know which company really takes safety seriously.
Don't get me wrong, it would be great if all brokers did that sort of "safety awareness consulting" or "15-seconds safety basics education" to the end-user, but from what I've seen it's rather marginal. Customers want the cheapest (or second cheapest), safety is the authorities' exclusive business... and we know it can be a total joke in some countries, partly because of a lack of resources.
