Aviation historian John Brown found photographic evidence in March that Whitehead made a powered flight over Connecticut in 1901, "two years, four months, and three days before the Wright brothers."
The relevant section of House Bill 6671 reads, "The Governor shall proclaim a date certain in each year as Powered Flight Day to honor the first powered flight by [the Wright brothers] Gustave Whitehead and to commemorate the Connecticut aviation and aerospace industry."
In 1968, Connecticut declared Whitehead the “Father of Flight,” recognizing his contributions before there was evidence of his powered flight. Governor Dannel Malloy is expected to sign the new bill next week.
Widely described as "first in flight," even on North Carolina license plates, the Wright brothers made their historic 852-foot, 59-second flight at Kitty Hawk, N.C. on Dec. 17, 1903.
Historians have long known that several individuals and groups were working on flying machines around the same time, including German immigrant Whitehead.
But some historians remain unconvinced that Whitehead ever got off the ground. Though there are surviving written accounts, the photographic evidence is compelling but not definitive.
Connecticut has a long aviation history, and Sikorsky Aircraft Corp., maker of the Black Hawk helicopter, has headquarters just miles from the site of Whitehead’s flight.
Whitehead's plane had bat-like canvas wings and was called "The Condor No. 21," and Brown said he flew it over Bridgeport, Conn. at a height of 50 feet for an estimated 1.5 miles on the morning of Aug. 14, 1901.
