Narrative:

I observed a B777 exit runway xxl at and stop prior to clearing the runway. He called ground control and received no response due to the actions of the; just on position; instructor and developmental who were in the midst of both a position briefing (instructor to developmental) and unplugging and replugging into the headset jacks to the proper positions for instructor and developmental. I was monitoring their position as controller in charge/coordinator and heard the B777 call and receive no response. I told them that the B777 was calling them. The B777 stopped movement when no response was received. The aircraft was still not clear of runway xxl when this occurred. I was also watching a second B777; on short final for runway xxl and determined there would be no time for the first B777 to clear the runway in time for the other B777 to land so I went directly to the local controller and pointed out the conflict and said to send the B777 around. Neither the point out; nor the verbal warning were acted upon. The B777 continued past the landing threshold and into the flair when the pilot of the B777 initiated a go-around on his own. At the time there was a GA transition aircraft (PA-28) approximately 1 mile north of the departure corridor for runways xx heading southbound along the highway. As the second B777 was observed to go around; the local controller gave the B777 a heading of 280 and climb to 3 thousand feet. He then instructed the GA transition aircraft to make a right 360 degree turn. Traffic was exchanged between the missed approach aircraft and the GA aircraft. I then observed the B777 make a left turn in the vicinity of the maneuvering GA aircraft and then return to a westerly heading. Willingness of controllers to take under advisement the supporting input from others in the tower environment and always having a plan ready when things don't work out. The heading given to the missed approach aircraft was ill advised.a divergent heading to the B777 of 265 degrees would have been more suitable due to the location of the transitioning aircraft.

Title: Tower Control reporters describe a go-around event and developing conflict when a B777 on flair elected to go-around because previous landing traffic was not clear of the runway.

Narrative: I observed a B777 exit Runway XXL at and stop prior to clearing the runway. He called Ground Control and received no response due to the actions of the; just on position; instructor and developmental who were in the midst of both a position briefing (instructor to developmental) and unplugging and replugging into the headset jacks to the proper positions for instructor and developmental. I was monitoring their position as CIC/Coordinator and heard the B777 call and receive no response. I told them that the B777 was calling them. The B777 stopped movement when no response was received. The aircraft was still not clear of Runway XXL when this occurred. I was also watching a second B777; on short final for Runway XXL and determined there would be no time for the first B777 to clear the runway in time for the other B777 to land so I went directly to the Local Controller and pointed out the conflict and said to send the B777 around.

At the time there was a GA transition aircraft (PA-28) approximately 1 mile north of the departure corridor for Runways XX heading southbound along the highway. As the second B777 was observed to go around; the Local Controller gave the B777 a heading of 280 and climb to 3 thousand feet. He then instructed the GA transition aircraft to make a right 360 degree turn. Traffic was exchanged between the missed approach aircraft and the GA aircraft.
