The observation deck closed long before 9/11. IIRC, I think the closure had to do with people taking the elevator up to the FAA floor, or the stairs up.
I remember the last few houses on Neptune Road. Pretty run down, but the owners wouldn't sell to Massport.
The neighborhood didn't survive because it was right under the flight path and runway threshold, and once jets came to Logan, living there became untenable. This was before jet engines had hush kits installed, or evolved into being much quieter. A Boeing 727 at 15000 pounds of thrust originally produced 165 decibels of noise.
Not a lot before then
However in the 1970's it was very popular
in June 1974 -- just before I left for Texas to attend graduate school -- I remember the formal visit of the le Concorde to BOS
A fairly big crowd was in the tower when it landed and when it took-off on a wild and crazy race across the Atlantic
le Concorde took off from Logan at the scheduled take off of the Air France 747 from Paris to Logan -- le Concord sans paying passengers (but there were some observers) zipped across the Atlantic to Charles de Gaulle Airport (IATA: CDG) -- the pilots and cabin crew had a nice lunch -- then then hopped back across the Atlantic and landed at Logan before the Jumbo made the one-way trip CDG to BOS!

Racing against a Jumbo
"At the invitation of the Massachusetts Port Authority. 02 flew to Boston on June 13 to take part in the dedication of the new John Volpe international terminal. The Paris-Boston crossing set a new record at 3hr. 9min., and this was followed the next day by a rapid return flight to Miami.
On June 17, 02 showed its paces to spectacular effect. It took off from Boston at S.22a.m. and, at almost the same time, an Air France Boeing 747 left Paris en route for Boston. The two aircraft crossed when the 747 was 620 miles out of Paris and 02 was nearly 2,400 miles out of Boston. Despite the Concorde turn-round time at Paris being extended to 68 minutes because one passenger could not be found, at the end of its return flight it landed at Boston 11 minutes ahead of the 747. Five hundred businessmen from Brazil, the USA, West Germany, France, and Britain sampled and approved of supersonic travel on these two series of flights, and an estimated crowd of 100,000 people came to see the aircraft while it was on view at Boston, causing the biggest traffic jams ever known there."
after the Concord landed -- the still hot plane was parked next to the "new international terminal" (aka old Terminal E) and they let the crowd get close enough to plane to feel the heat radiating from the fuselage and engine cowlings
That was a plane!! and BOS was the perfect launch pad due to its ability to get a supersonic plane -- going supersonic faster than any East Coast airport
Unfortunately idiot NIMBYs in places such as Neptune Road kept the Concord from more than a handful of subsequent flights.
