Most airlines which suffer a 'hull loss' DO NOT go out of business. There are, on average, about 50 - 60 'hull losses' suffered by airlines world wide a year. How many have failed? For every apparent failure following an accident there a hundred, hundreds even, which do not. The number of airlines which have gone out of business following a 'disaster' (say a fatal accident killing passengers)over the years is also minimal and the reasons for the failures which did occur were complex. The 'disaster' may have been the 'trigger' but other, mainly pre-existing, circumstances caused the failure.
