Context: Peter C. Masak (August 17, 1957 – May 22, 2004) was an engineer, inventor, and glider pilot.  He graduated with a Bachelor of Applied Science degree in Mechanical Engineering in May 1981 from the University of Waterloo, Ontario Canada.  He earned his glider pilot license at the age of 16 and his power pilot license at the age of 18, the minimum ages for both.  Peter was a Canadian soaring record holder and represented Canada and later the United States in the World Gliding Championships.  He logged almost 2000 hours of glider flight time.  He was living in West Chester, Pennsylvania with his wife Adrienne and their three children when he died. DUATS, or Direct User Access Terminal Service is a weather information and flight plan processing service contracted by the Federal Aviation Administration (FAA) for use by United States civil pilots and other authorized users.  The DUAT Service is a telephone- and Internet-based system which allows the pilot to use a personal computer for access to a Federal Aviation Administration (FAA) database to obtain weather and aeronautical information and to file, amend, and cancel domestic IFR and VFR flight plans.  The DUAT Service provides direct access to weather information via a National Airspace System (NAS) Data Interchange Network II (NADIN-II) interface to the Weather Message Switching Center Replacement (WMSCR) System and the Air traffic control (ATC) Facilities for filing flight plans.  The pilot users can interface the DUAT Services via the FTS-2001 toll free telephone numbers or via an Internet Interface into the Contractor's Facility. Doris Grove is an American world record breaking glider pilot, flight instructor, and a member of the U.S. Soaring Hall of Fame.  She was an early pioneer of ridge soaring in the Ridge-and-valley Appalachians in the 1970s, ultimately setting three world records flying gliders there, and becoming the first woman to earn the FAI 1000 km Diploma.  She was also a stunt co-pilot in the 1999 film "The Thomas Crown Affair". George B. Moffat Jr. is an author, twice world champion glider pilot, and a member of the U.S. Soaring Hall of Fame.  He began flying airplanes in 1953, gliders in 1959, entered his first national soaring competition in 1962, and was still an active competition pilot as of 2008.  Before competing in sailplanes, he compiled a winning record in International 14 foot Dinghy racing and is still an active sailor. The Thomas Crown Affair is a 1999 American heist film directed by John McTiernan.  The film, starring Pierce Brosnan, Rene Russo and Denis Leary, is a remake of the 1968 film of the same name.  The film generally received positive reviews.  It was a success at the box office, grossing $124 million worldwide. Richard H. Johnson (January 10, 1923 – July 23, 2008) was a glider pilot, aeronautical engineer and prolific writer of articles for gliding magazines.  He was an 11-time U.S. National Champion glider pilot, 9-time US Soaring Team pilot at the Soaring World Championships, held two World Gliding Records and is a member of the US Soaring Hall of Fame.  He flew for 70 years and logged over 14,000 flying hours, including over 10,000 hours of non-powered flight time in sailplanes.  He authored over 100 articles on soaring and flight tests of gliders. A practical test, more commonly known as a checkride, is the Federal Aviation Administration examination which one must undergo in the United States to receive an aircraft pilot's certification, or an endorsement for additional flight privileges.  The name refers to the portion of the examination in which the candidate being examined flies in an aircraft with the Designated Pilot Examiner or other authorized examiner to demonstrate competency in the skills that are required for the certification.  Although "checkride" is the most commonly used term, it is considered informal and is technically known as a Practical Test by the FAA and in all its literature, and the specific objectives which the candidate must meet are called the Practical Test Standards, or PTS. Karl H. Striedieck II (born April 7, 1937 Ann Arbor, Michigan) is a world record setting glider pilot, a member of the U.S. Soaring Hall of Fame, and an active Holocaust denier.  He was an early pioneer of ridge soaring in the Ridge-and-valley Appalachians in the 1960s, ultimately setting nine world records flying gliders there.  He was selected for the U.S. national soaring team 12 times, and won a silver medal in the world championships in 1978 and 1983. Thomas L. Knauff (born 1938) is an American writer, glider pilot, flight instructor, Federal Aviation Administration (FAA) Designated Pilot Examiner, and a member of the U.S. Soaring Hall of Fame.  He was an early pioneer of ridge soaring in the Ridge-and-valley Appalachians in the 1960s, ultimately setting five world records flying gliders there.  He was the stunt pilot in the 1999 film "The Thomas Crown Affair". In the United States, a Designated Pilot Examiner (commonly referred to as a DPE) is a senior pilot designated by the FAA to conduct oral examinations and inflight or flight simulator checkrides (collectively called "practical tests") with pilot applicants to determine their suitability to be issued a Pilot Certificate or additional rating on their Pilot Certificate.  Certain DPEs also have authority to issue Flight Instructor Certificates and associated additional ratings.  At the completion of the testing procedures, DPEs issue a "Temporary Airman Certificate" (pilot certificate) with the new qualifications or ratings, to be followed by a regular, credit-card-like certificate from FAA Airman Records following review of the certification file.
