This is undoubtedly the finest space shuttle kit I have ever constructed. I try to make my models as historically accurate as possible, and the Airfix 1:144 Space Shuttle was a beautiful foundation to make a museum quality replica. The kit contains an impressive array of decals, and the instructions are well illustrated. A stand is included which displays the shuttle in a unique "flying" position. The pieces have fine molding and fit together nicely. I should mention that Airfix molds their parts in grey, not white, so the orbiter, external tank, and SRBs must be painted their proper colors, unless you want an entirely grey model. There are of course several seams where the two fuselage pieces meet, but they are easily fixed with a bit of modeling putty. This model has the most detailed payload bay cargo out of any kit I have built. Unfortunatley, it doesn't have the kind of detail to satisfy the modeler going for a really accurate look, but it is certaily finer than some of the other payload bay representations I have seen out there. Like all shuttle kits, the Airfix has its problems. The first, is the fact that the intertank is not ribbed. There is a decal included in the kit which is supposed to represent this ribbing, but I think it looks cartoonish, and a serious modeler will need to create this detail with sheet styrene, or something like that. I was a bit dissapointed to see that there was no cockpit interior, but no 1:144 kit has that feature. Then there is the problem with the windows. Of the five shuttles I have built, all of them had issues with fitting the cockpit windows. The experience I had with the Airfix windows, was the worst out of any model. I couldn't get the windows for this kit to even remotely fit into their proper place. After spending literally hours trying to get them in, I gave up and scratch built my own. I don't know if MY particular windows were just molded poorly, but in any case, I did not have fun with those. Nevertheless, there are other components of the model that were so pleasing to me, that the window problem hardly mattered. In my opinion, the Airfix model is the finest replica in the 1:144 scale, and should be the top choice for a professional modeler, but also makes a very attractive kit without any scratch built enhancements.
