The Unseen: Dark of Night Is No Time to Improvise

NTSB investigation reveals spatial disorientation, but the full story offers deeper insights into a tragic accident.

Key Takeaways:

  • A Cherokee 140 crashed at night shortly after takeoff from Canyonlands Regional Airport, killing all four family members onboard.
  • The NTSB attributed the accident to the pilot's spatial disorientation resulting from a loss of visual reference in the darkness.
  • Contributing factors included the pilot's failure to activate runway lights, initiating a steep turn immediately after becoming airborne, and not monitoring instruments, which led to an unnoticed descent into terrain exacerbated by high density altitude.

Moab, utah lies nestled in a bend in the Colorado River, a green dot in a Martian landscape of ochre plains and low rocky outcrops that resemble the protruding vertebrae of buried monsters.

Sixteen miles northwest of Moab is Canyonlands Regional Airport (KCYN). Its runway, 100 feet wide and 7,360 feet long, is oriented 03/21. All of the airport’s buildings are at its north end, alongside the highway that leads to Moab.
