When you picture an airplane, a pretty familiar shape comes to mind. A long narrow body with two main wings sticking out from the middle, a pair of smaller wings on the back end, and a tail fin in the rear sticking straight up. The wings may be straight or swept to the back, but you wouldn't picture them sweeping forward, would you?
Sure, some fighter jets have wings that change position, and older planes might have an extra pair in the front, but you wouldn't have a backward wing. Well, tell that to the X-29. This experimental aircraft was developed by NASA and the US Air Force back in 1984! Date: 2022-04-19
