This package was compiled by the FAA Alaskan Region Public Affairs Office in Anchorage and sent to FAA managers with a memo from Paul Steucke dated March 5, 1987. It gathers material on the November 17, 1986 sighting by the crew of Japan Air Lines flight 1628: a news release, pilot and controller transcripts, crew interviews and radar analysis. The FAA concluded that it could not confirm the event. It attributed the second radar target to a split, uncorrelated return from the JAL Boeing 747 and planned no further investigation.

Federal Agencies Digitization Initiative Still Image Working Group - August 201 o I. INTRODUCTION Context The Technical Guidelines for Digitizing Cultural Heritage Materials: Creation of Raster Image Master Files represents shared best practices followed by agencies participating in the Federal Agencies Digitization Guidelines Initiative (FADGI) Still Image Working Group for digitizing cultural heritage materials. This group is involved in a cooperative effort to develop common digitization guidelines for still image materials (such as texhial content, maps, and photographic prints and negatives) found in culhtral heritage instihltions. These Guidelines were prepared by members of the working group during the winter of 2009-2010. This document draws substantially on the National Archives and Records Administration's Technical Guidelines.for Digitizing Archival Records f or Electronic Access: Creation o.fProducLion Masler Files - Rasler Images (June 2004 ), but has been revised and updated in several areas to reflect the clment recommendations of the working group and to reflect changes that have occuned in the digitization field during the last five years. Readers will find updated sections covering equipment and image perfonnance metrics, quality management, and metadata in this revision. For more information on the activities of the FADGI Still Image Working Group, please see http://wwv.; .digitizationguidelines.gov/. Purpose One of the tasks of the FADGI Still Imaging Working Group is to develop digital imaging guidelines that encourage and reflect collaborative digitization practices among federal agencies (and other interested institutions) in order to provide the public with images of uniform quality, and to provide a common set of practices and technical benchmarks for digiti7Mion service providers and manufacturers. In the context of the work of the F ADGI Still Imaging Group, some of the primary objectives of these Guidelin es are to: • Provide an approach to digiti zation that is practical today • Describe technical parameters that promote a "well-defined" imaging environment • Provide a consistent approach to imaging and metadata collection that will be appropriate for a wide range of outputs and purposes • Define a common set of quality or perfonnance metTics to be used in describing and evaluating the digital object, as well as methods of validating those measures to defined requirements Lay the groundwork for issues the Still Imaging Working Group intends to focus on in the coming months for potential incorporation into these Guidelines , including: metric aims and limits for imaging performance and quality specifications; color encoding accuracy; master and derivative file fonnats; transmissive image analysis targets; full lifecycle quality management plan; objective and subjective image performance analysis, and embedded/minimal metadata, among others These Guidelines define approaches for creating high quality digital copies of originals used primarily for facilitating online access and hardcopy reproduction. They may be considered appropriate for preservation purposes (to create copies that could replace the original), but this largely depends on the local or internal policies of an organization. Therefore, the recommendations in this document may not be appropriate for all preservation uses (for example, scientific analysis). Master files These Guidelines provide technical approaches to the creation of raster image (pixel-based) master files. In creating master files , the primary objective is to produce digital images that look like the original items and to create a "reasonable reproduction" without enhancement. However, practice may vaiy from institution to institution regarding the amount of processing or editing that is perfonned on master files.
