The development and rigorous flight testing of the Messerschmitt Me 163 Komet are documented extensively in the Luftwaffe test centre Arbeitsberichte works reports originating from the central testing ground (Erprobungsstelle) at Rechlin. These primary documents trace the developmental history of the aircraft from its early glider tests to its operational deployment as the world's first combat rocket-propelled interceptor. The Bundesarchiv manages the original military records for the Technical Air Armament directorate. You can search their online Invenio Database using the archival signature RL 3 to find specific technical reports and test records related to the Komet while the Rechlin test and work reports are also available for download. While specific Rechlin test logs and technical handbooks are officially catalogued, direct digital downloads require navigating specific archival databases.The Archivportal-D offers integrated access to various state archives such as the deutsche digitale bibliothek, where you can locate specific entries (such as the Me 163 B-Flugzeug-Handbuch). For independent archival research, expert resources like Rob de Bie's Me 163 Archives provide detailed inventories and breakdowns of where specific Reichsluftfahrtministerium (RLM) documents are held; eg the Me 163 B handbook manual is available in translation as a pdf download at the NASM link on Rob's pages.

..that the development of the Me 163 be pursued more vigorously than has been the case to date. The difficulties with the power plant have proved to be a major cause of delay. In addition, resolving the issue of the landing gear appears to be a matter of urgency. For increased endurance and improving takeoff characteristics the development and testing of takeoff assistance aids is essential. The questions of road transport (ie salvage) following off-airfield landings and a towing aircraft for repositioning by air (air transfers) require clarification.
