I didn't know this, but guessing that something like this happened is precisely why I brought it up. The fix for a broken safety culture in aviation isn't arresting mechanisms so that it's impossible to crash: it's addressing whatever series of events and incentives led to the captain making that decision, whether that means providing extra training, or finding the source of pressure from his superiors to avoid the diversion.
It is probably the case that Indian airline aviation has actually made these changes now. If so, it is a dramatically better intervention than your proposal for an arresting mechanism at one airport. India received the highest grade for airline safety last year.
> the alternative would be to find another rickshaw driver who limits the number of kids to 5. sure, it will be expensive but human lives should have more value than a 100-200Rs/month savings.
Why stop at only that 100-200Rs/month savings? There are probably many other sources of avoidable safety risk in India. What percentage of a poor person's income would you dedicate to more expensive safety improvements?
