On December 23, 1907, the Signal Corps issued Specification No. 486 for a heavier-than-air flying machine and requested bids. The specifications were sent to the Wrights. They were strict and nearly impossible with the existing technology. Now, the race was on, and the Wright brothers got hard at work creating their military flyer.

After over a year of work, the Wrights finished the Wright Military Flyer. This airplane had a shorter wingspan, longer propellers, was set higher off the ground, and had a different gear ratio compared to the original Wright Flyer.
