Well the long haul over water flight I was on today, simply did a cabin announcement stating not to use them or to put them on charge.
I guess that will work for awhile while the Feds and airlines get their act together.
My wife couldn't understand why/how so I explained to her in homemaker terms that while on-charge was like having a dripping faucet, a drop at a time, and putting your thumb over the tap, after a while the pressure builds up and the water will spurt out in one big shower
