It's not just the 100 miles past their destination.
They were out of contact for at least 74 minutes.
No response to numerous ATC calls - ignored the autopilot chime for destination - no CC contacts to check ( this is SOP every 20 minutes for most airlines over here)
Very surprising that they did not get an F16 awakening.
Even so a much more dangerous situation occurred this week with a Delta flight from Rio to Atlanta.
They landed on the taxiway instead of the runway!150 pax who were very lucky nothing else was on that taxiway (at night but unusual for taxiway to be quiet at ATL)
Interesting that the media are all over the 'sleeping' incident but little mention of the Delta flight.
Be glad when the week is over and it won't be 3rd time (un)lucky.
