NASA started a several months-long series of flights on 3 August to identify the physiological impacts of flying in high-performance military aircraft on the human body.
The flights are being conducted at NASA's Armstrong Flight Research Center at Edwards Air Force Base in California and will take place over 160 flight hours. The tests are managed by the NASA Engineering and Safety Center at Langley Research Center in Virginia.
During the tests researchers will measure the breathing of five NASA pilots flying in F-18A/B and F-15D aircraft, while they use different equipment types and experience different flight conditions. The flight conditions that will be tested include benign environments, typical in instrument proficiency training, to more strenuous environments, such as those found in high altitude, aerobatic manoeuvring and combat manoeuvring, according to NASA.
In recent years, the US Navy and Air Force have been perplexed by an increase in the number of pilots experiencing physiological events during flight across a variety of aircraft. Symptoms from physiological events include cognitive impairment, numbness, tingling, lightheadedness, behavioral changes and fatigue.
Data collected will just serve as a baseline for comparison because NASA's aircraft still use the legacy technology of a Liquid Oxygen System as opposed to newer military aircraft that utilise an Onboard Oxygen System.

Seapower Staff GROTON, Conn. — General Dynamics Electric Boat, a business unit of General Dynamics, was awarded two U.S. Navy contracts this week with a total value of $251 million, the company said in an Oct. 1 release. The first contract is a $215.7 million modification to a previously awarded contract, the cumulative value of which, if all options are exercised, could be more than $1 billion. Electric Boat will provide planning yard, design agent, engineering services and technical support for in-service submarines and submersible systems. The second contract is a $35.3 million cost-plus-fixed-fee contract for Reactor Plant Planning Yard services for the submarine fleet and Support Yard services for the Navy's Moored Training Ships. “The shipbuilders of Electric Boat are proud to be a partner to the U.S. Navy, and continue to execute our mission to provide our sailors with the advantage that helps protect our Navy and our nation,” said Kevin Graney, president of General Dynamics Electric Boat. “We continue to work to hire, train and develop future generations of shipbuilders as we continue to deliver the Virginia class of fast attack submarines and move toward full-scale construction of the Columbia class of ballistic missile submarines.” https://seapowermagazine.org/general-dynamics-electric-boat-awarded-251-million-in-navy-contracts/
