It is undoubtedly tragic for their employees that airlines, especially in such numbers, go under but this is the reality of the world we live in. He's hardly dancing around people made redundant sticking his tongue out and slagging them off, he's just asking for a list of airlines that have gone under this year. Interesting reading? Yes it could be considered so. Interesting doesn't necessarily mean joyous. You seem to be quite fond of leveling shame at people kick the tires. Grow up.
You'd be happy to have a list of companies that have done well so is the done thing just to ignore the ones that havn't? I hope to god that you are not in a position of power in any business because if you're prepared to sweep under the carpet the fact that airlines are dropping like flies then who knows what you'd be capable of.
EDIT: I'd put a big banner up here saying "SHAME KICK THE TYRES" but then I'd end up looking a bit silly...
