The seemingly parentless kids are noise enough, thank you
As someone who takes at least one long haul trip each month I can attest to the fact there are already enough noise generators on board what with all those seemingly abandoned children who derive some sort of pleasure from running up and down the aisles, screaming awakening sleeping passengers, knocking arms whose attached hand is often carrying a glass filled with liquid and causing the long suffering cabin crew additional hassles during trolley service.
Then someones sweethearts discover the light and call buttons to complete the cabin crews work days.
I have seemingly developed quite an effective 'angry stare' technique that gives all but the most reckless child second thoughts on passing my seat. In the event this fails, my feet are equally adept at causing little Johnny to trip with similar effect.
If an adult passenger made proportionately as much noise as these unruly kids they would be restrained and confined to their seats.
All we need in the cabin, to go along with those little bastards who make a habit of hanging over the back of the seat in front of you are a bunch of adults shouting in to cell phones describing the cloud formations the aircraft is passing.
Cell communications should be limited text messaging only and the femto cell emitting a 'vibrate only' instruction to further minimise additional sounds.
The only relief we can expect is that the charges will be so high that only the expense sheet gang in Business or First classes will be persuaded to call.
