This half-scale model of Concorde in British Airways livery was situated directly across from One Times Square.
The model was built by L&L Tooling

Below some more pictures and info on the construction of the Times Square model.

L&L Tooling was commissioned to build this 1/2 scale model of the flagship supersonic Concorde for British Airways.

The model is made of fibreglass and steel and measures 102 ft. long with a 42-ft. wing span, weighing 24,000 lbs.

The finished Concorde was shipped to New York and placed four stories above the most famous and busiest intersection in the world: Broadway and 42nd Street, directly across from One Times Square (site of the New Year's Eve Ball Drop).

The Concorde was first sculpted by L&L Tooling technicians, then moulds were taken. From these moulds, and a lot of work, the fibreglass replica emerged.

The model was removed in 2001, when the lease on the site expired, and it was re-developed. It was donanted to the Cradle of Aviation museum on Long Island
