Many thanks for the positive responses to AEHS Newsletter #1. AEHS member Lee Stohr corresponded that he uses modern 3D printing and pattern making in his casting business. If you want to see art, take a look at his 1920s supercharger intercooler casting:

Animations can save hundreds of words of descriptive text and elucidate complex mechanisms.  From engines to valve trains to propellers, the AEHS has members who have contributed some wonderful CAD drawings and animations:

A four-pass average of 531 mph wasn't quite fast enough to beat Lyle Shelton's 528 mph by 1% so Rare Bear still holds that record, but Steven Hinton Jr. captured the fastest Piston Single Engine speed on one of the passes with the mouse motor in Voodoo:

Would have loved to have been there as I am sure the sound had been amazing, with a symphony that neither my dinky home computer nor any artificial audio system can capture or reproduce. For the uninitiated, the roar of the crowd at the ball field is heard or felt by more than your ears. Think about the collective watt energy it takes for all those people to produce that sound. I don't have to explain to the folks that have made it to the Races in Reno-- the exhaust barking, the props propping, the air shearing...

The Bugatti 100P was an experimental amateur-built, twin-engine, single-seat, tail wheel monoplane built as a replica of the Bugatti-DeMonge 100P, a 1930s era air racer that was never flown. The original resides at the EAA Museum in Oshkosh, Wisconsin. A group of EAA "home build" enthusiasts using the original airframe as a pattern, reverse engineered and constructed a complete air frame of similar materials as the original. Modern Suzuki Hayabusa motorcycle engines substituted for the unobtainium original straight-8 Bugatti engines. The plane crashed during the third flight and the pilot and project leader Scotty Wilson was killed. A link to the he NTSB report is below and a much more informative analysis of the accident by the La Rêve Bleu Team can be found at the second link below.Before flight testing, the replica was displayed at the "Art of Bugatti" exhibit at the Mullin Auto Museum located in Oxnard California. Following the 2015 AEHS convention in San Diego California several of the conventioneers traveled up the coast to view the beautiful handiwork.

YouTube has a plethora of recent content on the Komet, when I typed in "Me-163":

Long time Rolls-Royce employee, historian, noted author, AEHS member, and host organizer of our 2013 AEHS Convention in the UK, Dave Birch, died from a stroke in March, 2018. Dave's wife Linda has relayed how much Dave enjoyed the AEHS and his many American friends, and Linda thanks the gracious AEHS women who made her Convention time so wonderful. Thanks for everything, Dave.
