Riding a DL DC-9 into BOS 04L many moons ago, I heard engines windup as if for a GA well before the MM. We banked fairly sharply off to the right, but did not climb.
Then another fairly sharp bank left, with descent resuming. I was seated at a left window and saw we were lining up on 33. Rolled out of the bank right over the threshhold for a neat touchdown.
While taxiing in the Cpt apologized for the "USN carrier approach" but explained that another aircraft failed to expedite his departure on 04L, and the tower re-cleared us for 33.
The other aircraft was a FAA bird.
