An engaging series as long as you dispense of any knowledge of ATC & flight protocols. So if you're literally flying blind (pun intended) into this series, then it will be entertaining, but if you have any knowledge of security SOPS for air safety, then this will just leave you shaking your head. Each increment in the plot requires a suspension in belief to the point that it no longer follows reality to any extent, & that journey may end very early for some, but I congratulate anyone for surviving the full seven episodes.
