Only in Boston by Duncan J.D. Smith

24 Charlestown & East Boston as a sign of respect. Few passengers notice them, however, and there is nothing to say why they are there. In 2014, when United Airlines moved to gate B-27, they erected a new flag. JetBlue, which took over gate C-19, has retained United’s existing flag, which means there are now three flags flying. The fourth memorial to the events of 9/11 is one the flying public never sees. It is a daily security meeting attended by representatives from the airport, airlines, security and police. The meeting was inau- gurated on the morning following the attack and has continued ever since. Staff at Logan are determined that nothing similar will ever be- fall the airport again. The fifth memorial is Logan’s official public memorial to the vic- tims and stands on Logan Memorial Way in front of the Hilton hotel. Designed by Boston-based Moskow Linn Architects and unveiled in 2009, it consists of a modest square glass cube representing the twin towers, inscribed with the departure times of both aircraft. The two winding paths leading up to it recall the flight paths taken by the hi- jacked aircraft. Placing the cube on a hill encourages people to look up- wards and beyond the tragedy that happened here. Likewise the trees planted around the memorial impart something living and optimistic. Like most commercial airports, Logan has seen its fair share of conventional accidents. The earliest occurred on July 24th 1923, when Lieutenant Kitchell Snow (1899–1923) of the 101st Observation Squad- ron of the Massachusetts National Guard died after nosediving into nearby mudflats. In a twist of fate, Snow, whose grave at Forest Hills Cemetery (Jamaica Plain) is marked by a bronze eagle, had been the first pilot to land at the airport when it opened a month earlier. A fine view of Logan can be gained from Orient Heights to the north. Near the summit at 111 Orient Avenue is a 40-foot-high statue of the Madonna. Erected in 1954, it forms part of the US headquarters of the Catholic Don Orione order (see no. 6). Also visible from Orient Heights are the sludge digesters of the Deer Island Waste Water Treat- ment Plant. To find out how Boston was once provided with fresh wa- ter visit the Metropolitan Waterworks Museum at 2450 Beacon Street (Brookline). Housed in an original building of 1887, it features an im- pressive machine hall containing three huge steam-powered pumping engines. A memorial labyrinth unveiled on September 11th 2003 at Boston College in Chestnut Hill recalls 22 alumni lost in the 9/11 tragedy. A memorial unveiled in Boston’s Public Garden a year later commemorates the 206 people from Massachusetts killed during the attacks.
