Maybe as an extra but not as part of the film; it's not part of the prior five-film Coppola set, either. It is somewhat confusing, as Chef has orders to call in the airstrike if Willard and Lance don't return but he's too dead to carry them out. :) My assumption is that Willard did call it in...
My preference is the theatrical cut with the explosive air strike closing credits but that seems to be unavailable. When was the last time we saw those?
