After a recent visit to BOS, I noticed that Terminal B had undergone some construction work, making the western half wider. Comparing my BOS terminal silhouette to reference imagery, I could see that a few other changes had been made to various terminals as well, so I updated the terminals and converted the silhouette to my new color scheme.
Since BOS was one of my earlier terminal silhouettes, I also took the opportunity to clean up the entire drawing (mostly ensuring that parallel and collinear lines were, in fact, parallel and collinear).
I decided to include the landside terminal walkways this time, as they’re reasonably prominent in satellite imagery, and the terminal looked better with them.
