Yes, however, I am just shock that.

1) Boeing, being a multi-billion dollar company, with tons of experts personnel, allowed this obviously dubious, illogical, horrific, security-lacking design to pass the drawing board, implement it, and actually built it.

2) Like another post said if Boeing chooses to redesign the systems, i.e. separate the A/C from internet, by law they would need to redo all the extensive testing involved to launch this plane. I seriously doubt they will do this because many airlines are already restless to the delays of 787 and are cancelling orders. Boeing wants to get it out the door ASAP.

3) I can see the only solution they will do is to install a "Firewall" or "Software Security" - which translates into - HACK HEAVEN.

787 better just announce they will NOT allow passengers to use their internet system or otherwise I would not fly on it. Airline security screens bombs, not hacking ability.
