Was on the Internet Movie Car Database just now and the 1970 movie
Gas-s-s-s has been added, and now there is a clearer image of that movie's pesky Helldiver from the geting.se site:
http://www.geting.se/viewimage/image/295814-3126.jpgA lot more detail now: four-bladed prop hub, rear deck folded down, a bit of reddish orange paint below the star-and-bar (Reserve band?), and here's a real kicker: look below the cowl at the fuselage with the worn insignia in the background - does it look like it could be a
second Helldiver also with the folded-down deck? The plot thickens! I know some of this movie was shot in Socorro, NM, possibly at the institute where so many surplus airframes were expended in weapons testing (there are several F3H Demon tails scattered around in another shot), but could they have had a Helldiver(s) at that point? Or did MGM have this stashed on their back lot?
Over to you...
