Reality
This is a tragic accident, and my sympathies go out to all the families of those involved. The reality of our current world is that there are places where standards are different...and these may be for a number of reasons, including the poverty within that country. We should all assess our own risks and make choices based upon that, for example if I choose to go to an Indonesian nightclub I do so knowing that it is unlikely the safety standards are up to those in the UK, and I would scope out the exits more carefully as a result. Of course many of those involved will not have been in the position to make that judgement, so what is the solution? I do not have an answer to that, however I do believe we must not make the mistake of forcing our own values on those of other countries. For example in Thailand many times you will see 4 or 5 people on one motorcycle, simply they have no option, of course such behaviour would not be accepted or tolerated in the UK or US. As for the Mandala Airlines Captain sounds like a non issue not all countries enforce the same draconian cockpit door regs and if it is not in the critical stages of flight why not talk to a Flight Attendant? Wasn't there a USAir crew some years ago who let a cabin crew member sit on their lap for landing? A bit of a ramble I know but in summary economic realities do apply to aviation and once again sympathies to the families concerned
