Hezarfen Ahmed Celebi was a legendary Ottoman aviator of 17th-century istanbul, purported in the writings of traveler Evliya Celebi to have achieved sustained unpowered flight. The 17th century writings of Evliya Celebi (was an Ottoman Turk who travelled through the territory of the empire and neighboring lands over a period of forty years, recording his commentary in a travelogue called Seyahatname)) relate this story of Hezarfen Ahmed Celebi, circa 1630–1632:

"First, he practiced by flying over the pulpit of okmeydani eight or nine times with eagle wings, using the force of the wind. Then, as Sultan Murad Khan was watching from the Sinan Pasha Mansion at sarayburnu, he flew from the very top of the Galata Tower (in contemporary Karakoy) and landed in the Dogancilar Square in Uskudar (Scutari), with the help of the south-west wind. Then, Murad Khan granted him a sack of golden coins, and said: "This is a scary man. He is capable of doing anything he wishes. It is not right to keep such people," and thus sent him to Algeria on exile. he died there."

Measurements of the alleged launch height and flight distance are as follows:

The Galata Tower sits 35 m (115 ft) above sea level, the peak of its conical dome 62.59 m (205.35 ft) above ground level and 97.59 m (320.18 ft) above sea level.[3]
Dogancilar square is about 12 m (39 ft) above sea level.
The elevation change between the tower (takeoff) and the square (landing) is 85.59 m (281 ft).
The distance between the tower and the square is approximately 3.358 km (2 mi).[4]
Glide ratio required is 39:1.
