Alfred G. Piranian
May 27, 1947 - February 24, 2022

Alfred G. Piranian of Chalfont, Pennsylvania passed away at age 74 on February 24, 2022 in a plane crash.

Born Alfred George Piranian on May 27, 1947 in Lugano, Switzerland, he was the oldest of Alfred and Magdalena’s seven children. He graduated high school from Germantown Academy, going on to earn both his B.S.E. and Master’s degrees in Mechanical and Aerospace Engineering from Princeton University.

In June 1971, Al married Inger Jeannette de Haas. Their union would continue for over 50 years and produce five children: Edward, Heidi, Karen, Lori, and Lisa. Al was a devoted husband, son, father, and grandfather, and he took great delight in spending time with his immediate and large extended family. Later in life he was beyond thrilled to welcome 15 grandchildren, ranging today from college-aged to newborn. He cherished his grandchildren, showering them with love and attention in the time he was able to spend with them.

Al devoted most of his professional life to serving his country, in dual capacities both as a Navy civil service employee and as a Naval Reservist. Al began his career as an aerospace engineer for the U.S. Navy by working at the Naval Air Development Center (NADC) Warminster in Johnsville, Pennsylvania in 1967. When NADC closed in 1993 as a part of the federal government's base realignment initiatives, Al continued his work at Naval Air Station Patuxent River until his retirement in 2015. Over his 48-year service as an aerospace engineer working for the Navy, Al worked as a senior aerodynamicist on the design of the F-14, F-18, and the F-35. He was responsible for the airworthiness certification of all stores/weapons carried by the F-14 Tomcat, the Joint Standoff Weapon (JSOW) and the Joint Direct Attack Munition (JDAM) on the F/A-18 Hornet, and also finally on the F-35 (Joint Strike Fighter). He was a member of the NATO Air Armament Working Party and presented internationally. Al also served in the Naval Reserves, drilling at Naval Air Station Willow Grove and achieving the rank of Commander. He also flight instructed in the Willow Grove flying club, and in the last seven years of his life Al continued to pursue his interest in aviation by flight instructing at Doylestown Airport. He logged over 11,000 flight hours with his favorite airplane by far being the T-34B Mentor and was loved by numerous students.

Al was generous with his time and resources as he pursued an eclectic range of outside interests over the years. He rowed on the Princeton men’s varsity lightweight crew team for all four years of college. While completing work on his master’s degree at Princeton, Al served as a crew coach in the earliest years of Princeton's women’s varsity crew team. His lifelong dedication to Princeton rowing continued, as he served for decades as Treasurer of the Princeton University Rowing Association. Other pursuits of Al’s included a love of classical and choral music, coaching his children's sports teams, serving as a Boy Scouts leader for his son’s troop, teaching Sunday school, playing his violin in worship services, and singing in the church choir for many years. He had a great love of history, was a voracious reader, traveled as widely as possible, and enjoyed German cuisine wherever he could find it.

Above all, Al’s deep and abiding Christian faith shaped his life’s work and purpose on Earth and now he is with his Savior. Al was a long-time member of Hilltown Baptist Church and worshiped most recently at Covenant Presbyterian Church in Harleysville.

Al is survived by his mother Magdalena Piranian of Ambler, Pennsylvania; his wife Jeannette of Chalfont, Pennsylvania; son Ed Piranian and his wife Jennifer of Wasilla, Alaska; daughter Heidi Bauer and her husband Steve of Bethesda, Maryland; daughter Karen Burgman and her husband Michael of Fountainville, Pennsylvania; daughter Lori Mulcare and her husband Bobby of Greenwich, Connecticut; daughter Lisa Ferguson and her husband John of Lansdale, Pennsylvania; six siblings; and 15 grandchildren.

Donations in Al’s memory may be made to Mission Projects Fellowship, P.O. Box 209, Telford, Pennsylvania 18969. A memorial service celebrating Al’s life will be held at Hilltown Baptist Church in Hilltown, Pennsylvania on Sunday, March 13th at 2 pm, with a musical tribute beginning at 1:30 pm.

Brian Carlos Filippini
March 25, 1966 - February 24, 2022

Brian Carlos Filippini of the Chestnut Hill section of Philadelphia, passed away suddenly on February 24, 2022, age 55. He is survived by his wife of 28 years, Jennifer Leigh Filippini, his 3 children Remi (24), Carlo (20), Sante (20), sister, Alicia Filippini (Peter Gissing) and his niece Izabella Gissing and nephews Cooper Gissing and Nick Piner. Brian was preceded in death by his parents Charles and Norma Filippini.
Brian’s love of flying was a gift from his father Charlie who was an aeronautical flight surgeon with the Air National Guard. Brian’s passion for aviation blossomed in January 1988 when he took his first solo flight. Brian was a 4-year scholar athlete at The Ohio State University on a four year Track and Field scholarship. He received his degree in 1989 in Business Management, Logistics and Aviation. Brian met Leigh in Philadelphia at the Dickens Inn in 1990 after recognizing her as the girl he saw playing field hockey in the Ohio Stadium while he was running track. It was meant to be. They were married four years later in November in Cape May, NJ.  In 1997 Concord Management Group, a retained Executive Search firm was born as a result of Brian’s entrepreneurial spirit and love of life sciences and technology. The company has thrived under their joint leadership for the past 25 years and is the regional leader in the life science business. 
Brian and Leigh were so proud when their twin boys, Carlo and Sante, chose to attend their alma mater and are now studying at the Fisher School of Business. As proud parents, they had the pleasure and honor of attending Remi’s business school graduation this past December in Edinburgh, Scotland. Remi shares Brian’s love of life sciences and will be working as a Commercial Operations Analyst in the industry.  
In 2005, the dream of Chango Villa was completed in Cozumel Mexico. Chango Villa has been the epicenter of countless family, social and business gatherings, and was truly where Brian was happiest, especially surrounded by tequila, cigars, scuba, and mariachi music. Loving Mexico so much, Brian wanted to learn the native language to communicate respectfully, so within a year, Brian was speaking fluent Spanish.  Brian’s love of the outdoors began with his family in the Sierra Nevadas where he spent his childhood hiking, camping and skeet shooting. Brian carried his love of a rugged lifestyle and adventure to the East Coast where he incorporated it into the Filippini way of life.  Brian was known for his love of family and friends, his integrity, his commitment to his business and his passion for flying, a good cigar, a glass of Remy Martin, and a good conversation. 
 Family and friends are invited to attend a Celebration of Life on Saturday March 5, at 1:00pm at Wings Field Airport (Hangar # 2), 1501 Narcissa Rd, Blue Bell, PA 19422. In lieu of flowers, the family requests that donations be made to an organization near to Brian’s heart- Angel Flight East - a non-profit dedicated to providing free air transportation for those needing medical treatment far from home.

The single-engine plane that crashed in a Hilltown neighborhood Thursday evening, killing two aboard — including the plane's owner — was an instructional flight, according to National Transportation Safety Board investigators.

At least one of the people onboard had a private pilot's license and was training for a commercial license, the NTSB said.

NTSB investigators were in the neighborhood at Brittany and Victoria lanes Friday collecting information and examining what is left of the aircraft, agency spokesman Keith Holloway said.

One of the dead was identified as Brian Filippini, 55, of Philadelphia, who is listed in FAA records as the registered owner of the Beechcraft 35-C33 Debonair. 

It is unknown if Filippini was flying the plane at the time of the crash. The Bucks County Coroner's office had not yet confirmed the identities of the dead as of Friday afternoon.

This news organization spoke to a family member while attempting to contact Filippini on Friday. He confirmed the death, but declined further comment.

NTSB investigators will also gather radar data, weather information, aircraft control communications, maintenance records and pilot medical records. They will speak to witnesses and review raw video posted on social media.

This is a photo of the 1965 Beech 35-C33 single engine plane that crashed Feb. 24, 2022 in a Hilltown neighborhood, killing two people aboard
Doorbell video cameras captured the fiery crash, which occurred shortly before 5 p.m. in the development of single family homes located near a Pennridge middle school.

In raw video posted on social media, the sound of an engine sputtering can be heard seconds before the plane dropped out of the sky and exploded, sending thick black smoke cloud over the neighborhood. 

The plane took off from Wings Field Airport, a general aviation airport in Blue Bell, Montgomery County, at 4:13 p.m. Thursday and landed at the Doylestown Airport nine minutes later, according to, a flight tracking website. 

At 4:26 p.m. the plane departed Doylestown headed to Gunden Airport, a privately owned airport outside of Sellersville, according to the website. The FAA confirmed in a statement the plane took off from Doylestown headed to Gunden.

The plane crashed just yards from a home. No injuries were reported on the ground and no homes were involved in the crash, but the plane struck an unoccupied vehicle, Bucks County spokesman James O'Malley said. There was also some damage from debris to nearby homes, said Hilltown police Chief Chris Engelhart.

On Friday morning, the scorched remains of the plane remained on the corner, underneath a charred street sign and surrounded by caution tape and a barrier meant to contain any fuel spill.
