sure but at the end of the day the decision is mostly made by a single (or multiple) human being(s) who can make honest mistakes or be arrogant (this sounds like what happened in the Mangalore case). in any case, having an arresting mechanism would safe lives. no matter how many hours of additional training is given, they can still make mistakes. even if it doesn't get used in 100,000 uses but if it saves 10 lives on the 100,001th use, it's worth it.
> India received the highest grade for airline safety last year.
do you mind providing some sources for that? afaik there were no airlines accident last year anywhere that resulted in a loss of live.
> 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?
sure. i'm giving out examples of poor safety. nowhere did i say this is the leading cause of avoidable deaths. this is one of the many i have seen there.
