| | B-17 Flying Fortress history |
 | | Project 299, as Boeing called it, got started on August 16, 1934, only eight days after the company had received the official government request for a prototype multi-engine bomber to be ready by August of the following year. |
 | | The Boeing designers took advantage of the knowledge they had gained in building the civil transport Model 247 and in developing the Model 294 bomber. |
 | | The first of these planes, the YB-17, took to the air on December 2, 1936, and the others were delivered for testing between March 1 and August 5, 1937, to the 2nd Bombardment Group. |
