BB Torch 9800 Smartphone :: How To Really Power Off?

Q) How can you power the phone down?

When the phone is off, it seems that a simple tap of the Red power button turns the phone on again. This seems like a design flaw. All other non BB devices that I know off require you to hold the power button for a couple of seconds to turn it back on.This prevents the phone from accidently being turned on.

Let me explain a use case. When you are flying you have to turn your phones off.So the normal procedure is to hold the red hang up key and the phone will power down. This is as expected.Assume you then put the BlackBerry device in the seat pocket in front of you.Midway through the flight you hit your knee against the seat pocket.The red power button it tapped during this process.The phone now powers on.You are about to land and your phone rings.The flight attendant and the passengers all give you unpleasant looks through no real fault of your own.This type of issue has occurred a few times.

I realize you can go in and manually turn off phone connections but this is an extra step.Turning the phone off should take care of this and there should stay off until the user wants to turn it on.
I see this behaviour on my 8310 and 8900 and 9800.I hope there is something simple I'm missing??
