Creating an accurately shaped canopy for a static F14 replica is certainly possible, using 3mm or 5mm Plexiglas (Perspex) or other suitable transparent (or tinted) acrylic sheet, which would need to be vacuum formed to shape, probably by a firm that specialises in making large mouldings and panels for illuminated shopfront panels and advertising signs. A lot of carefully controlled heat and air pressure is required. First, though, a "buck" (male interior form) would need to be made, probably of wood. This "buck" could best be carved by inputting the shape data from the aircraft plans into a computerised carving machine. My firm uses "3D Studio Max" software to do similar work. This is how one-off double curvature canopies for full size prototype airceaft replicas are made for such events as the Trade Sections of events like the Farnborough Airshow. Hollywood studios and their subcontractors do this sort of thing on a daily basis, but it has to be remembered that they have budgets of hundreds of thousands of dollars (or more) for each item they produce. There is also the issue of durabilty. The backlots at Universal Studios, for example, are a treasure trove of decaying props used for a few weeks of photography and then discarded. Close inspection of these shows that they were made of ferrous metals, softwood and plastics that were not chosen for a long life. Even if a replica is to be kept indoors, it would need to be of much more robust construction than a scale model for display in a showcase. Personally, if commissioned to build a replica F14, I would tend towards a triangulated frame made of aluminium tubing, to which were attached outer panels either handmade from composites (probably a combination of glass fibre and carbon fibre) or, where a metallic finish was necessary, using aluminium or stainless steel sheet shaped on a wheeling machine. The labour costs would be high, since the project would require very experienced craftspeople from a number of trades. It would take that team two years to finish the job, and I would exprect the final account to be in seven figures. And that is before one factors in the transportation costs, and the acquisition and fitting out of the display space, and the ongoing management bills. This might all be viable for an established museum, but they would probably prefer to acquire a "genuine" example of the aircraft (which in the case of the F14 I believe would be cheaper). As keen modelmakers, we might complain when a "must have" new product carries a price tag of $500, but in some contexts we do not know how lucky we are.
