I just noticed that the official diagram of LGA does not show the location of the Marine Air Terminal nor does it show the new control tower. Is the new tower in operation yet? I happened to notice a "Sea World Shamu" SouthWest aircraft coming-in to land yesterday. It ressembled a whale. It probably arrived on Rwy 31. There seems to be no flights in/out of LGA in the early mornings as Passur shows none. Does LGA shut-down at night? It's site says it's open 24/7. See you on Kids Day.
