Airport filling begins.

The state locates Boston’s new airport on the 134 acres already created for port development.  The city leases the airport in 1928, and resumes filling in 1930, creating an additional 140 acres by 1932.  The city transfers the airport in 1941, and the state begins a huge expansion in 1944, extending fill over Governors and Apple Islands and across the flats to Winthrop, completing that project in 1946.  Massport takes over airport management in 1959, and fills Wood Island Park in 1967-69, the Bird Island Flats in 1968-73, and completes the filling in the 1970s.  The airport is by far the largest area of made land in Boston – a total 1,629 acres of which 1,413 are in Boston and 216 in Winthrop.
