First, I want to say, that historycally the FIRST is important only in case, if it triggers some processes. For excample despite, it's clear that vikings were clearly before Columbus in America, that is not very important historically, cause it was just only known for small group of vikings and that knowledge died with those people. So, for the motored flight Wrights are important. The real first is important just like historical fact.
The reason, I write this is that the person who made the very first successful motored flight, was estonian (my countryman), who lived in swiss this time. The name was Alexander Liwentaal and the flight was made in England. It lasted 80 meters (longer than Wrights first flights) and ended when the pilot tryed to land the plane. Plane crashed, pilot broke his both legs, and the man was forced to live in wheechair.
Plane: Kind of a strange biplane with the wings located after each other (not above). 24m² and engine with 24hp. The flight was made in 1898 in England. Excact story there:
http://www.ekspress.ee/arhiiv/2001/34/aosa/kuum15.html It has some pictures so it's worth to watch despite the text is only in Estonian. Scroll down a bit until You find some pictures (and that's not the story about the Ikaros

).
The finding was done by three man Johannes Tilk, Toivo Kitvel and Frits Gerdessen, who are writing a book about Estonian aviation.
