Illinois Valley Regional Airport Walter A Duncan Field (VYS)

Illinois Valley Regional Airport Walter A Duncan Field (VYS/KVYS) operates as north-central Illinois' premier general aviation facility serving Peru and LaSalle County, opened in November 1985 near the strategic intersection of Interstates I-80 and I-39, named honoring World War I U.S. Army Lieutenant Walter Duncan who founded the original La Salle-Peru Airport and Airways before his 1983 death. Located just 8 miles from Starved Rock State Park and the historic Illinois Waterway system, the facility hosts the renowned TBM Avenger Reunion & Salute to Veterans each May—America's largest gathering of World War II torpedo bombers celebrating the event's 10th anniversary in 2025 with United States Air Force F-16 Fighting Falcon VIPER Demo Team performances.

Comprehensive general aviation facilities include two paved runways with the main strip extending nearly 6,000 feet accommodating diverse aircraft operations, while Midwest Aero FBO provides full services including Jet A and Avgas fuel, aircraft maintenance, hangar rentals, and transient aircraft support. The Illinois Valley Flying Club, established in 1987 and headquartered at the airport, offers aircraft rental and flight training services, while corporate aviation, recreational flying, and agricultural operations utilize the facility's professional infrastructure complemented by pilot-controlled lighting for extended operational hours.

Operational characteristics emphasize diverse aviation activities where the annual TBM Avenger Reunion attracts aviation enthusiasts nationwide to witness authentic World War II aircraft demonstrations alongside modern military jet performances, creating significant economic impact for the Illinois Valley region through aviation tourism. The facility maintains Chicago ARTCC approach and departure services (123.75/259.1 frequencies) while agricultural aviation operations share airspace patterns requiring coordination during growing seasons when crop-dusting activities peak throughout surrounding fertile Illinois farmlands.

Strategic importance extends beyond regional connectivity to preserving American military aviation heritage where the TBM Avenger Reunion demonstrates living history through flyable World War II aircraft, connecting modern audiences with wartime sacrifice while supporting veteran organizations and military appreciation events. The airport anchors Illinois Valley tourism development leveraging proximity to Starved Rock State Park, the Illinois Waterway, and interstate highway access, establishing Peru as a significant aviation destination demonstrating successful integration of general aviation infrastructure with heritage tourism, economic development, and community pride in American military history.
