Lagâri Hasan Çelebi's rocket flight depicted in a 17th-century engraving.
|Known for||Legendary manned rocket flight|
|Relatives||Hezârfen Ahmed Çelebi (brother)|
Evliya Çelebi purported that in 1633, Lagari Hasan Çelebi launched in a 7-winged rocket using 50 okka (140 lbs) of gunpowder from Sarayburnu, the point below Topkapı Palace in Istanbul. The flight was said to be undertaken at the time of the birth of sultan Murad IV's daughter. As Evliya Celebi wrote, Lagari proclaimed before launch "O my sultan! Be blessed, I am going to talk to Jesus!"; after ascending in the rocket, he landed in the sea, swimming ashore and reporting "O my sultan! Jesus sends his regards to you!"; he was rewarded by the Sultan with silver and the rank of sipahi in the Ottoman army.
Evliya Çelebi also wrote of Lagari's brother, Hezârfen Ahmed Çelebi, making a flight by glider a year earlier.
Istanbul Beneath My Wings is a 1996 film about the lives of Lagari Hasan Çelebi, his brother and fellow aviator Hezârfen Ahmed Çelebi, and Ottoman society in the early 17th century as witnessed and narrated by Evliya Çelebi.
The legend was addressed in an experiment by the television show MythBusters, on November 11, 2009, in the episode "Crash and Burn"; however, the rocket constructed for the TV show did not adhere closely to Evliya Çelebi's descriptions and the final design did not attempt to utilize materials of the period; the team noted that Evliya Çelebi had not sufficiently specified the alleged design used by Lagâri Hasan and said that it would have been "extremely difficult" for a 17th-century figure, unequipped with modern steel alloys and welding, to land safely or even achieve thrust at all. Although the re-imagined rocket rose, it exploded midflight.

So, unfortunately with myths of this kind, there's no one single version of the story, which means that there's no one definitive rocket design for us to build. ... First of all, the 140 pounds of black powder that he's supposed to have used as his propellant would have been extremely dangerous to handle, not to mention containing all of that explosive force and converting it to thrust would have been extremely difficult. ... And second, the materials that we have available today, all the modern steel alloys, and all the fabrication techniques, like welding — he didn't have any of that.
