there was a merger between the Glenn Martin Company, the Wright Company, the Simplex Automobile Co, and the General Aeronautical Corp.... and then they rolled out the Wright-Martin Model R powered by a 150hp Hall-Scott A-5A.

Indian Model O light weight twin bike strapped tight between the wings. The US. Navy and Martin -with the US. Army as observers- tested this contraption as a way to give its crew an escape option in case they had to land behind enemy lines

The theorized advantages of having new, lightweight motorcycles available to pilots along the front were numerous.

 A motorcycle provided pilots with a solution for forced emergency landings. Either due to mechanical or combat failure, often times pilots had to land their aircraft in remote locations far from any available fuel or assistance, but with another vehicle they could quickly escape any dangerous environments or simply retrieve whatever they needed to get back in the air.

In the case of a pilot who survived an aerial attack, the ability to return to friendly territory was another attractive incentive despite the added weight of a motorcycle. 

With the life expectancy of a WWI pilot being only around 20 days near the front, having a pilot return from battle rather than wind up a POW or casualty was particularly of interest.

Ed Roy, after restoring his 1911 Simplex, he set out to build a fully operational 1/6 scale model of each body style Simplex offered in 1911.

the windshield, being flexible, seems to be a recent creation... but would they allow it at the Pebble Beach Concours? I doubt it. But nothing was mentioned about it, because Murphy's Law realized it was the only thing I wanted to know

Notice in the above description the roadster is said to have a "mechanician's" seat. What the hell? I've learned a new word! According to Wikipedia a mechanician is an engineer or a scientist working in the field of mechanics, It is also the term by which makers of mechanical automata use in reference to their profession.
