This is an interesting discussion... if a little complicated.
1: The primary existence of the NASM was originally, and still is as far as I know, a national repository of aviation TECHNOLOGY, with history a significant, but distant, second. This is the reason why some aircraft in the collection, notably Douglas the XB-42 and XB-43 are preserved as fuselages only (wings sawn off!), as the interesting technology was in the fuselage. There are other such examples (DC-7 and RF-101 forward fuselages, etc.). I must admit that I don't subscribe to the idea of preserving the part, instead of the whole, but there you go... that's what the museum was set up to do, and it's doing it at an industry leading level. Nationality of the technology was not important, just the technology itself.
2: NASM has not primarily concentrated on the axis types. The biggest single project was the enormous undertaking of B-29 "Enola Gay"... this took about 20 years. Only two axis types have received significant attention in the past twenty years, the Seiran, and the Arado 234. Everything else has been either preservation, or tidying up for display in Udvar-Hazy.
3: The history of the B-17D "Swoose" after Dec.8th is a far more interesting and significant story in and of itself. It participated in the first US night bombing raid of WWII. Was pieced together in the aftermath of damage during raids on the Japanese, and then acting as an executive transport all over the Pacific region to many very important people including future president, LBJ. It is a significant aircraft, and is very worthy of complete restoration, but NASM has been so focused on the very difficult, and extraordinarily expensive efforts to get Udvar-Hazy together it has been stretched to the fullest. For the last five or six years no new complete restoration has been started, just work to finish those already under way, and preservation/touch up work to get other airframes ready for display in as-is condition.
4: NASM is not perfect... no museum is, but without their effort, so many very important aircraft and historical artifacts would no longer be with us. They are a credit to the nation. To say that they should restore all of our aircraft before restoring any of those from other nations is also extremely short-sighted, and makes no sense whatsoever. If we were talking art... would that mean restoring "Dogs at Cards" before looking after the "Mona Lisa"? I think not. There isn't a single aviation museum in the world which has a better reputation or collection than NASM, so give 'em a break for goodness sake.
Sincerely,
Richard Allnutt
