With minimal fill they could easily make 15L/33R a viable runway without blocking any boat traffic. They should do that and get rid of 9/27. Not just to allow taller buildings, but its reaaaally not such a great idea sending massive jets directly at your downtown or trying to land by flying right past downtown. Its a single run way as well. 15/33 already has another runway pointing in that direction so youre not creating a new route. Jets fly up the mystic to keep noise down as well. I think this should be seriously considered not only is 9/27 unnecessarily dangerous, but jet noise is also going directly over downtown, the common, back bay, south end, roxbury, dorchester...etc. With 2 run ways in one direction and 2 in another it would be simpler from an operations perspective as well.
We already know people would bitch... same ppl who refused the red line because of “undesirables”... A runway already is going in that direction so tough shit. Safety issue, done. This plus a people mover and the new terminal would bring Logan into position to reach its potential of the 21st century without it being a total clusterf**.
9/27 is critical for Logan. Removing it would be disastrous from an operational standpoint and I can’t imagine such an idea would ever be seriously suggested or considered.
