OKLAHOMA CITY — Colleagues of a missing pilot who was volunteering for a pet rescue operation when his plane failed to land at a Texas airport have completed the rescue flight in his honor.

Missing pilot Dr. Bill Kinsinger left an Oklahoma City airport on Wednesday bound for the Austin area to pick up a disabled dog. His plane never landed. The Coast Guard was still searching Friday for 55-year-old Kinsinger, who was last seen over the Gulf of Mexico.

Fellow volunteers with Pilots N Paws made the trip Thursday, transporting a disabled senior husky to its temporary home in Oklahoma. From there, the dog will be taken to Las Vegas for medical care.

Kinsinger’s fellow volunteers told KOKH-TV on Thursday that the missing doctor would have wanted the rescue to go ahead.
