Airframe remains one of Crichton’s few novels not adapted to film. Crichton stated this was due to the great expense needed to make such a film. 

No Killer Plot. Not much action. But there is a pace to it.

It is a story of the investigation of a seemingly normal plane crash, until the investigators witness the condition of the interior cabin. And the fact that the pilot is behaving so strangely accentuates the strangeness of the entire incident.

Make sure that you have a whole day set aside to read the last half of the book.  You won’t put it down and will have to wait for the end for the ‘reveal’

AirFrame, Michael Crichton
