That baseball game revisited

I now realise, watching the clip for about the fourth time and finally noticing the giant map in Mission Control, that the plane is off the East coast travelling North-East at the time of the shuttle launch. This means that I can ignore time zones, but it can't be Dodgers Stadium. I think that I'll say it's Gotham City Stadium.

OK, so when do baseball games usually start and roughly how long is a typical game?
