Yes it certainly is off the topic and not of much relevance here.But just to let you know , around 15 - 17 years ago , an Indian Airlines aircraft was hijacked by a single male pax who concealed a weapon in a leg brace/cast and got through security saying that it was part of his brace/cast.He was subsequently killed by the Black Cat commandos.You really can't blame the CISF for doing their job eventhough it may be a bit irritating at times.These days you really cannot take things easy especially with security....
