That's correct. However, there was nothing critical to repair. The
alternator tripped, that's all. The engine's still turning, the
weather's severe clear (albeit night), plenty of gas; I saw nothing of
any urgency. Even if the battery totally died, I could circle Danbury
and get a light gun.

With a dead battery, you'd not only have no radio, but also no lights and
no transponder. What makes you think the tower would even have a clue you
were there?

With one of the pax not feeling well, I'd be thinking getting on the
ground at the first reasonable opportunity.

... and then what?

Get the airplane fixed and/or rent a car to get your pax home.
