Born in Massachusetts, Mark’s passion for flying emerged early. A graduate of the U.S. Naval Academy, he became a naval aviator, earning the call sign “Gucci” for his flair and precision. As a Blue Angels pilot from 1997 to 1998, flying as #4 in the Delta formation, Mark captivated audiences with his skill in the F/A-18 Hornet, notably during the 1998 Pensacola Beach Air Show.

His time with the elite squadron showcased his excellence, performing high-intensity maneuvers with finesse. After his naval service, Mark joined JetBlue Airways, rising to Captain and earning admiration for his professionalism and calm demeanor in the cockpit.

Mark’s impact extended beyond flying. Known for mentoring aspiring aviators, he shared his expertise with warmth and humility. His involvement in the aviation community included hosting events like his son’s sixth birthday at a Blue Angels practice, reflecting his generosity. Colleagues and passengers alike recalled his ability to make every flight memorable, with one X post noting, “We became better humans in his presence,” highlighting his profound personal influence. Mark’s adventurous spirit led him to waterskiing and boating, often enjoying Perdido Key with fellow aviators.

Diagnosed with glioblastoma, a rare and aggressive brain cancer, Mark faced his illness with the same courage he displayed in the skies. Despite undergoing treatment, he succumbed to the disease, leaving behind a legacy of resilience.

The Andover community and aviation world mourned his loss, with tributes on X describing him as a “terrific pilot” and a “wonderful person.” A YouTube tribute emphasized his role as a devoted family man and loyal friend, underscoring the depth of his impact.

Mark is survived by his loving family, whose names are withheld for privacy. A memorial service is being planned, with details to be announced through Farley Funeral Home in North Andover.

In lieu of flowers, the family requests donations to a glioblastoma research fund or an aviation scholarship in Mark’s name, reflecting his passion for flying and commitment to advancing medical research. His legacy will live on through the Blue Angels’ precision, JetBlue’s skies, and the countless lives he inspired.

Mark “Gucci” Dunleavy’s life was a testament to excellence, kindness, and adventure. Rest in peace, Mark, your wings will forever soar in our hearts.
