Monmouth Executive Airport (IATA: BLM, ICAO: KBLM, FAA LID: BLM) is a privately owned, public use airport located in Wall Township, Monmouth County, New Jersey, six miles west of Belmar and east of Farmingdale (from which its code BLM is derived). The National Plan of Integrated Airport Systems for 2011–2015 categorized it as a general aviation reliever airport. Covering 850 acres at an elevation of 153 feet (47 m), the airport features two asphalt runways, with its main runway being one of the longest private runways in the United States at 7,345 feet. Previously known as Allaire Airport until 2003, it was sold in 2013 to Wall Aviation, a consortium led by Alan Antaki. Antaki also owns Sussex Airport one mile southwest of Sussex in Wantage Township, New Jersey.

In an analysis by the Regional Plan Association in 2011, Monmouth Executive scored highly as a potential airport for airline flights to expand capacity and relieve aviation congestion in the New York area.

Monmouth Executive Airport was established in 1938 by Edward Brown Jr., a self-taught aviation enthusiast and former Navy pilot. Brown acquired approximately 700 acres of land in Wall Township from the widow of newspaper columnist Arthur Brisbane. He personally cleared the land, reportedly using a World War I army tank borrowed from the Belmar American Legion to level the initial runway. After serving as a Navy pilot during World War II, Brown returned to manage and expand the airport, which became a cornerstone of general aviation in New Jersey.

In 1948, Brown pioneered the world’s first fly-in drive-in theater adjacent to the airport, a novel attraction that allowed both cars and small planes to watch movies. The theater, which could accommodate 500 cars and 25 airplanes, operated until September 7, 1966, and remains a significant part of the airport’s historical legacy. Brown’s entrepreneurial spirit also led to other ventures on the property, including a quarry, golf driving range, amusement park, and nightclub, though these were less enduring.

Following Brown’s death in 2006, the airport was managed by his family, with his stepson Jack Taylor overseeing operations. In 2013, Wall Aviation, a consortium of investors and aviation enthusiasts led by Alan Antaki, purchased the airport from the Brown family. The new owners implemented significant upgrades, including 24/7 operations, enhanced security, and infrastructure improvements, aiming to transform the facility into a modern jetport catering to corporate aviation. The transition was not without controversy, as Wall Aviation evicted tenants such as skydiving and banner towing operations to prioritize business aviation, prompting concerns from local operators about the impact on traditional Jersey Shore activities like aerial advertising. Despite these changes, the airport has strengthened its position as a key aviation hub, with investments in runway repairs and plans for further development.

Monmouth Executive Airport covers 850 acres (344 ha) at an elevation of 153 feet (47 m). It has two asphalt runways: 14/32 is 7,345 by 85 feet (2,239 x 26 m) and 3/21 is 3,508 by 50 feet (1,069 x 15 m).
