Took the kids to Fly Day at Paine Field today. Paul Allen flys some of his warbirds. We saw his people fly an F-6 Hellcat, a P-47 Thunderbolt and an Ilyushin II-2M3 Shturmovik (with a nose and belly made of armorplate!).

One thing I didn't don't know about Paul Allen's Flying Heritage Collection is that almost of of his toys have valid certificates of airworthiness and are ready to fly — tow them out of the hangar, fuel up and off you go. The planes mostly have absorbent blankets underneath the engines soaking up the oil drips. The radial engines have buckets. The B-25 has 4 or 5 buckets under each engine. Apparently, radials leak of lot of oil.

Here's the kids with on of the planes.

Paine Field also hosts the ME-262 Project (http://www.stormbirds.com/project/general/introduction.htm) — these guys are building 5 brand-new ME-262s:



Production has been strictly limited to five aircraft: once these five are complete, no more will ever be produced, now or in the future.

The airplanes are being manufactured as a continuation of the basic Me 262 design. In fact, they have even been assigned factory serial numbers drawn from the werknummern sequences used on the original 1945 production lines.

Great pains are being taken to produce aircraft which are not simply replicas, but rather true serial production representative aircraft in every possible respect. Virtually rivet for rivet, the new aircraft are duplicates of the original Me 262. With the ability to examine and copy components from a vintage source, the standard of authenticity has been exactingly maintained.

Of course, the original design suffered from some well-known weaknesses, most notably dealing with the engines and landing gear systems. These areas were studied carefully, and certain subtle modifications have been directed for operator safety and reliability. A cursory visual inspection would never reveal them, however, as these internal modifications have been tightly integrated into the original design characteristics of the aircraft.

In essence, the new Me 262s are simply representative of a natural evolution of the airframe. They are being manufactured using many of the same techniques as the originals (by hand from raw materials), and are to be precision duplicates, even down to the four nose-mounted Mk 108 cannons. The only noteworthy concession will be in the area of engine selection.

Clearly, an engine change was necessary to make this project viable, as the original Jumo 004B powerplants were decidedly temperamental and prone to frequent failure. After careful consideration of a wide variety of available engines, the General Electric J-85 / CJ-610 was selected as the replacement for the vintage Jumo powerplants.

Thanks to an innovative engine mounting concept, the J-85s are to be buried deep inside carefully-engineered castings of the original engine, so that correct visual appearance will be retained. The Jumo housings are also necessary to maintain the correct nacelle weight since the J-85 is a much lighter engine than its German predecessor.

The propeller hubs sometimes leak buckets, too.

That really is a great museum and as you say almost every plane there is currently fly able. The day we were there there were a couple of mechanics working on one of the plane's engines right in the showroom.
