Harrington Emerson, President, Emerson Institute, to Vice Admiral William S. Sims, Commander, U.S. Naval Forces Operating in European Waters
June 23, 1917
Rear Admiral William S. Sims,
Racing men have enough common sense not to give running horses any more weight to carry than is absolutely necessary. They don’t want to lose races.
A thousand pounds of nerves and muscles and bones in the terrific physical and nervous excitement of the race is put in charge of a 100 pound jockey, who is fully capable of handling the animal.
The battle airplane among vehicles corresponds to the race horse among beasts of burden. The supreme quality is speed to which both factors of safety and durability are sacrificed.
Its get away speed
Its straight away speed
Its climbing speed in altitude per second
Its radius of outbound flight and return
Its load of bombs
are lessened by every extra pound in the flyer.
A pound of gasoline carries a plane about one mile. 60 – 80 lbs. more gasoline means 60 – 80 miles more flight.
Why, therefore, are six footers, weighing now 160 to 180 lbs., and only kept down to these weights by constant training, accepted and trained by the Royal Flying Corps, when 100 lb. pilots would do as well?
Moreover, the 100 lb. man, being smaller, is less likely to be hit and could, without increase in weight, carry thicker armor over head and heart.
There is a strong agitation now to increase the air service. Let this movement be coupled with common sense on the part of the authorities, and as to this you can give much help.
Yours very truly,
