The mission involved stealing the key card from Devon "Awesome" in order to plant the bug inside the pacemaker. To do this, they have to get him drunk, but end up tranquilizing him. The mission is a success and the bug gets planted. But Devon was the surgeon for the operation. If he is still unconscious and missing his key card, how could he have performed the surgery the next morning?
In speaking of the GLG-4000's lost radio signal, it is said that at least 6 feet of solid steel would be needed to block that signal. Discounting reflection issues, radio waves are, for the most part, stopped through either absorption by a non-metallic non-conductor or blocking by a generally metallic conductor. Rock absorbs some portion of a radio's waves, the thicker the layer of rock the larger the portion absorbed. It would take a strong signal to get through, say, 100 feet of solid rock. But a mere layer of aluminum foil (being a conductive barrier) could stop that same signal. Actually, the copper mesh from a screen door would suffice.
In Alex Forrest's Swedish passport the birth date is 29 Jul 1974 and the personal number is 790729-9361. However, the first six digits of a personal number are the birth date in yymmdd format, so it should be 740729-9361.
