Dovetail joint dovetails completely from view. The sliding dovetail is a method of joining two boards at right angles, where the intersection occurs within the field of one of the boards, that is not at the end. This joint provides the interlocking strength of a dovetail. Sliding dovetails are assembled by sliding the tail into the socket. It is common to slightly taper the socket, making it slightly tighter towards the rear of the joint, so that the two components can be slid together easily but the joint becomes tighter as the finished position is reached. Another method to implement a tapered
Mitre Corporation Mitre occupied in September 1959. After the SAGE project ended in the early 1960s, the FAA selected Mitre to develop a similar system to provide automated air traffic control. The result of the project formed the National Airspace System (NAS), that is still in use today.
