The simplest explanation is usually the answer.
These 2 pilots failed to answer around 10 different air traffic controllers as they were flying through different ATC zones, over a time period of 77 minutes. Either they had the comm turned off, they were out of the cockpit or they were sleeping. Either way the real answer will probably get them fired so they will never admit to it. At first they said that they were arguing over NTSB policy which is a comical excuse, so they changed it to the laptop excuse. The laptop excuse might be plausible for a one pilot plane, but it is not believable for 2 pilots approaching a destination and flying right by it. My guess is that they were sleeping. Because the pilots are the only ones who know what occurred in the cockpit that day, they probably won't ever admit the truth.
