found this interesting, after the go around, another jet blue was cleared, while DL51 was on a mile and a half final, difference this time, the 2nd jet blue did an immediate.
ATC at Boston handled pretty calm and cool.

A Delta Airlines Airbus A330-200, registration N855NW performing flight DL-59 from London Heathrow,EN (UK) to Boston,MA (USA), was on final approach to Boston's runway 33L.

A Jetblue Bombardier C-Series CS-300, registration N3125J performing flight B6-531 from Boston,MA (USA) to San Juan (Puerto Rico), was cleared to line up runway 33L at 16:40:21Z immediately after the preceeding departure had departed and aligned with the runway at 16:41:38Z, when DL-59 was about 2.8nm before the runway threshold.

Tower cleared DL-59 to land on runway 33L at 16:40:48Z.

At 16:42:00Z tower cleared B6-531 for immediate takeoff from runway 33L advising the arriving traffic was 1.5nm behind them (ADS-B data show DL-59 about 1.9nm before the runway threshold at that time).

At 16:42:32Z tower instructed DL-59 to go around, the crew acknowledged.

B6-531 started to accelerate for takeoff at 16:42:45Z when DL-59 was about 0.7nm before the runway threshold.

DL-59 began to climb again about 0.15nm past the runway threshold at 16:43:05Z, at that time B6-531 was accelerating through about 110 knots over ground about 0.55nm down the runway. Climbing through 500 feet at 16:43:28Z DL-59 began to turn to the right onto a diverging trajectory, B6-531 was climbing through 400 feet about 0.13nm past the runway end, the minimum separation between the aircraft according to ADS-B data was 100 feet vertical and 0.89nm horizontal.

DL-59 positioned for another approach to runway 33L and landed safely about 12 minutes after the go around. B6-531 continued to destination for a safe landing.

The FAA reported: "An air traffic controller instructed Delta Air Lines Flight 59 to perform a go-around at Boston Logan International Airport because another aircraft was departing at the same time the Airbus 332 was attempting to land. The event happened around 12:45 p.m. local time on Sunday, Oct. 27. There was no loss of safe separation."
