James Glaisher and Henry Tracey Coxwell, September 5, 1862

James Glaisher was chosen to carry out experiments and Henry Tracey Coxwell was employed to fly the balloons by the British Association for the Advancement of Science. On September 5, 1862, taking off from Wolverhampton, Coxwell and Glaisher reached the greatest height achieved to that date. Glaisher lost consciousness during the ascent, his last barometer reading indicating an altitude of 29, 000 ft and Coxwell lost all sensation in his hands, but managed to pull the valve-cord with his teeth before losing consciousness. Later calculations estimated their maximum altitude at 35, 000 to 37, 000 ft
