United Airlines said its installation of satellite-based equipment will begin in the second half of this year, with all planes equipped by the end of 2015.
This free guided tour will begin at 5:30 pm at the permanent Language of the Birds installation, designed by Bay Area artists Brian Goggin and Dorka Keehn and located at the intersection of Columbus and Broadway in North Beach.
The Interior Department granted the company permission to begin "certain limited preparatory activities" -- including work related to the installation of a blowout preventer -- on August 30.
