Were Gliders invented before airplanes?
Yes, some early attempts at flying were done with gliders both manned and unmanned. The Wright Brothers were not however the first to fly a heavier than air, controlable, powered aircraft. That honour goes to Jacob Broadbeck nearly 50 years earlier… Here is but one bit of information on Jacob: http://www.texasescapes.com/…/…acob-Brodbeck.
