On August 5, 2008, about 1941 Pacific daylight time, a Sikorsky S-61N helicopter, N612AZ, impacted trees and terrain during the initial climb after takeoff from Helispot 44 (H-44), located at an elevation of about 6,000 feet in mountainous terrain near Weaverville, California. The pilot-in-command, the safety crewmember, and seven firefighters were fatally injured; the copilot and three firefighters were seriously injured. Impact forces and a postcrash fire destroyed the helicopter, which was being operated by the U.S. Forest Service (USFS) as a public flight to transport firefighters from H-44 to another helispot. The USFS had contracted with Carson Helicopters, Inc. (CHI) of Grants Pass, Oregon, for the services of the helicopter, which was registered to CHI and leased to Carson Helicopter Services, Inc. of Grants Pass. Visual meteorological conditions prevailed at the time of the accident, and a company visual flight rules flight plan had been filed.

From a fire policy of prevention at all costs to today's restored burning, Between Two Fires is America's history channeled through the story of wildland fire management. Stephen J. Pyne tells of a fire revolution that began in the 1960s as a reaction to simple suppression and single-agency hegemony, and then matured into more enlightened programs of fire management. It describes the counterrevolution of the 1980s that stalled the movement, the revival of reform after 1994, and the fire scene that has evolved since then. Pyne is uniquely qualified to tell America’s fire story. The author of more than a score of books, he has told fire’s history in the United States, Australia, Canada, Europe, and the Earth overall. In his earlier life, he spent fifteen seasons with the North Rim Longshots at Grand Canyon National Park. In Between Two Fires, Pyne recounts how, after the Great Fires of 1910, a policy of fire suppression spread from America’s founding corps of foresters into a national policy that manifested itself as a costly all-out war on fire. After fifty years of attempted fire suppression, a revolution in thinking led to a more pluralistic strategy for fire’s restoration. The revolution succeeded in displacing suppression as a sole strategy, but it has failed to fully integrate fire and land management and has fallen short of its goals. Today, the nation’s backcountry and increasingly its exurban fringe are threatened by larger and more damaging burns, fire agencies are scrambling for funds, firefighters continue to die, and the country seems unable to come to grips with the fundamentals behind a rising tide of megafires. Pyne has once again constructed a history of record that will shape our next century of fire management. Between Two Fires is a story of ideas, institutions, and fires. It’s America’s story told through the nation’s flames.

System safety is a widely accepted management and engineering approach to analyze and address risks in complex systems in order to prevent accidents. Because software and computing systems are integral to most systems, software safety has become a critical component of an overall system safety effort. Software and System Safety discusses critical elements of the discipline of system safety and shows how software and computing systems fit in the system safety process. Software-specific aspects of the system safety process are addressed to show concerns common to complex systems. The many accidents and incidents presented in this book illustrate important lessons learned and show how software-related hazards can be misidentified, software risks can be improperly assessed, hazard controls may be misapplied, and software and system testing may not effectively verify that the risk had been reduced. The lessons learned come from a variety of industries and organizations, and include the author’s personal experience. The real-world lessons provided in this book can be used to improve existing software safety and system safety efforts, and can help when planning new system safety programs.

On March 23, 2004, about 1918:34 central standard time, an Era Aviation Sikorsky S-76A helicopter, N579EH, crashed into the Gulf of Mexico about 70 nautical miles south-southeast of Scholes International Airport (GLS), Galveston, Texas. The helicopter was en route to the drilling ship Discoverer Spirit. The captain, copilot, and eight passengers aboard the helicopter were killed, and the helicopter was destroyed by impact forces. The flight was operating under the provisions of 14 Code of Federal Regulations Part 135 on a visual flight rules flight plan. Night visual meteorological conditions prevailed at the time of the accident. The National Transportation Safety Board determines that the probable cause of this accident was the flight crew's failure to identify and arrest the helicopter's descent for undetermined reasons, which resulted in controlled flight into terrain.

On March 23, 2004, about 1918:34 central standard time, an Era Aviation Sikorsky S-76A++ helicopter, N579EH, crashed into the Gulf of Mexico about 70 nautical miles south-southeast of Scholes International Airport (GLS), Galveston, Texas. The helicopter was transporting eight oil service personnel to the Transocean, Inc., drilling ship Discoverer Spirit, which was en route to a location about 180 miles south-southeast of GLS. The captain, copilot, and eight passengers aboard the helicopter were killed, and the helicopter was destroyed by impact forces. The flight was operating under the provisions of 14 Code of Federal Regulations Part 135 on a visual flight rules flight plan. Night visual meteorological conditions prevailed at the time of the accident. The National Transportation Safety Board determines that the probable cause of this accident was the flight crew's failure to identify and arrest the helicopter's descent for undetermined reasons, which resulted in controlled flight into terrain. The safety issues discussed in this report focus on terrain awareness and warning systems for helicopters, flight control system training, flight-tracking technology for low-flying aircraft in the Gulf of Mexico, and preflight testing and maintenance checks for cockpit voice recorders. Safety recommendations concerning these issues are addressed to the Federal Aviation Administration.

On January 26, 2020, a Sikorsky S-76B helicopter, N72EX, being operated by Island Express Helicopters Inc. as a Title 14 Code of Federal Regulations (CFR) Part 135 on-demand flight, crashed into terrain in Calabasas, California. The pilot and the eight passengers died. One of the passengers was retired basketball player Kobe Bryant. Safety issues include the pilot's preflight weather and flight risk planning, the flight's entry into instrument meteorological conditions and the pilot's inadequate adverse weather avoidance, the pilot's spatial disorientation, influences on the pilot's decision to continue the flight into adverse weather, Island Express' incomplete implementation of its safety management system (SMS), the benefits of a mandatory SMS, the benefits of flight simulation devices for pilot training in adverse weather avoidance, the benefits of a flight data monitoring program, and the value of crash-resistant flight recorder systems in preventing future accidents. As a result of the investigation, the National Transportation Safety Board makes two new safety recommendations each to the Federal Aviation Administration and Island Express.

A U.S. Army HU-1A helicopter crashed at 1105 hours on 9 June 1960 while on a tactical mission. The crash site was in a mountainous area on the Fort Carson Military Reservation near Butts Army Airfield, Fort Carson, Colorado. One crew member and three passengers were aboard the aircraft at the time of the accident. The pilot and the occupant in the copilot's seat sustained spinal strains while the other two occupants received strains, abrasions, and cuts. The aircraft was examined at the crash site, and photographs of the wreckage and of all essential components and equipment were obtained during the course of the investigation. (Author).
