When Steve Austin has flashback memories of Oscar Goldman's face, the scenes are actually from the episode "The Peeping Blonde" which aired one week after this episode.
The radar plane reporting the crash site of Col Steve Austin is an EC-121 Warning Star and is the military variant of the Lockheed Super Constellation.
As Steve jumps from the Pick-up Truck and runs in the desert back to Broken Fork, he stumbles due to the pain in his arm, he gets up and starts running again with his arm hanging by his side. He slowly regains full momentum and this exact film looks eerily similar to that used in "Population Zero" when Steve after escaping from being in the freezer and with near frozen limbs starts running.
