Pilot Survives Flight Fraught With Dust and Drill Bits

As recounted by Duane Richens, with assistance from his son, Ken Richens.

One morning in the late 1960s, the owner of Basin Flying Service called to let me know that he had a rush order to fly four diamond drill bits to Moses Lake, Washington. The bits had to be delivered the same day because the rig was shut down waiting on them.
