A couple of corrections to the above post. HOW stood for Hercules On Water. The wingspan was 8 feet and the ski was called a "hydro-ski" 21 feet long and 3 1/2 feet wide on the full scale ship. The extension would be 10 feet max landing and taking off in moderate seas. There would be auxiliary wing floats at the outboard wing to serve as stabilizers and fuel pods holding 400 gallons. Interesting to note that the article contained a quote from Rear Admiral John S. McCain, Jr. concerning the remote deployment of Marines as an important instrument of national policy.
