I've been causing a bit of commotion about the pyro X-Wings on another thread, and thought I should do the same with the Y-Wings with a few thoughts I've had. The three pyro shots of the Y-Wings from ANH are a bit of mystery as to what ships were used. The consensus is that the death of Gold 5 above the Death Star is the triangles model, which the remains of still exist and were recently seen in a Profiles in History auction. And the only other known Y-Wing model is blue/gray, which some people believe was destroyed in one of the pyro shots, while others think was given to Alan Ladd Jr. So either the conclusion that most people draw is that there were one or two other pyro Y-Wings built, but there is a lack of pics of these models from that time period.
While watching the pyro footage of Gold 5 a few times, I noticed a few things. First of all, that we see a charge blow off the port engine of triangles with the supports and nozzle flying off, but we don't see the damage to that engine that is evident in the Profiles pics:
Gold 5 also does not immediately explode into a fireball like the other models, instead is drops out of frame after loosing the engine. Then the fireball appears, but the direction of the explosion comes from the bottom left corner of the screen and does not have any recognizable Y-Wing parts in the fireball. The fireball appears to be a separate filmed element composited over the Y-Wing footage. The shot is identical to how it is scripted in the fourth revised draft script, with the TIE fighter in the background, over the surface of the Death Star, the engine coming off, and the ship dropping down afterwards. But there is no fireball at that point, the script has Gold 5 communicating with Red Leader as he spirals down and crashes into the Death Star. It looks like they may have abbreviated Gold 5's death by adding the extra fireball element in to speed up the pace of the action. If triangles wasn't completely blown up at this point, it could have easily had its engine reattached to be used in another pyro shot.
That fully accounts for all the pyro shots if triangles and blue/gray are pyroed for the deaths of Gold 2 and Gold Leader. There would be no need for any mystery undocumented pyro models to exist. This assumes that it wasn't blue/gray given to Alan Ladd Jr, but TIE Killer, which was passed onto the current anonymous collector at some point. That is unless there is a source that can confirm that Alan Ladd Jr still has the model given to him by Lucas. If that is the case, then there is still another mystery pyro unknown to us.
Looking at the pyro scenes for Gold 2 and Gold Leader, I think Gold Leader best matches up to the damage we see on triangles in the Profiles pics and video. When Gold 2 bites it, the port engine flies off spinning in the foreground and the wing to it is still attached, while the wing on the Profiles pic of triangles is missing and replaced with clear plexiglass. The engine is also intact as it flies off screen, while half of the engine on triangles is missing on the Profiles pic. The cockpit and fuselage on Gold 2 also separate, with the fuselage falling out of frame while the cockpit continues its forward motion, while triangles appears to have the cockpit and fuselage still connected in the Profiles pics. However when Gold Leader dies, the engines are still attached up until the shot cuts away, but the model is noticeably on fire at that point and may have suffered more damage as it continued to burn after the cut in the footage. Triangles is missing a big chunk of the dorsal fuselage right behind the droid socket, and Profiles added a removable featureless piece to fill in the void as can be seen in the video interview. When Gold Leader blows up, the cockpit and fuselage are still attached, but the cockpit bobs up and down as it travels like it is only partially connected which is consistent the large chunk of triangles that is missing.
That's my explanation for what we see on film and from the known pics. Anyone have a different explanation?
I am confused on the engine lights for the lights. I was under the impression that only the hero Y-Wing TIE Killer had the lights installed, and that the pyros triangles and blue/gray did not have lights. We do see the lighted engines on TIE Killer in the approach on the Death Star with the black droid in back. But there is a shot through the cockpit of Vader's TIE Advanced just before he shoots down Gold 2, where three Y-Wings are in view and all three have engine lights. Did triangles and blue/gray have lights too, or was this TIE Killer composited three times in the frame? I had assumed that the surviving Y-Wing (Gold 7 in the EU) was TIE Killer because we see the engine lights. I haven't matched any other features of the surviving Y-Wing yet due to the size in the frame and the motion blur, is it possible it could be either triangles or blue/gray if they have lights too?
