This was Ed Flanders's (Bernie Ross) seventh and final appearance on the series. Sadly, Flanders died by his own hand at age 60 on February 22, 1995, which was 20 years and four days after this episode was first broadcast.
While this was the sole series appearance for Jo Ann Harris (Laurie Benedict), she did go on to receive second billing in Jack Lord's post-Hawaii Five-O project M Station: Hawaii (1980).
The Cessna 206 Super Skywagon piloted by Ed Flanders, registration number N29162 would be seen again in "McGarrett is Missing" and then again in "Dealer's Choice...Blackmail" piloted by John Ritter.
The scene with McGarrett's helicopter lifting off is recycled from the season five show "The Jinn Who Clears The Way."
When Ross lands the plane at the Lihue airport on Kauai, the head of the actual pilot in the seat beside him is seen just sticking up above the base of the window.
