The first airplane to take flight was built by the Wright brothers  in Ohio USA and was transported first to North Carolina and flown  for its first time there.
   Wh â¦ ile some argue that Santos Dummont (Brazilian) invented the  airplane while he was in France there is no evidence of any actual  physical works done to support the claim, there are no patents so  the credit goes to the Wright Brothers who filed the first patent.he first official airplane hop was in 1890, but the idea has been around since Da Vinci. Also, the first jet flight was in 1939, but the Germans only started using them in 1944. i don't know when it was invented. What about you.
