When Airwolf blows the blue and yellow MD500 out of the sky the exploding wreckage is red and white. The same exploding wreckage is shown when the second MD500 collides with the sheriff's Bell Long Ranger.
When Airwolf is flying above the Volcano, Dom states they got everything they need. He says he is inputting the data into the computer, as he does and the camera pans down, he is seen wearing a leather flight jacket. As it goes back to him sitting in the chair, he is back in his Airwolf flight suit.
