Francis Herbert Wenham and John Browning built an early wind tunnel for aeronautical research in 1871. It allowed wings to be tested systematically under controlled airflow. This experimental method was essential to later fixed-wing design, replacing guesswork with measurable aerodynamic evidence.

The wind tunnel is part of the hidden machinery behind modern metaphors of air, speed, and control. It also marks the shift from the poet's symbolic wind to the engineer's quantified current, a transformation many modern writers found both exhilarating and unsettling.
