I see a neighbor's hangar has two conventional fire extinguishers on
the wall. Not a bad idea, I'm sure. But for potential hangar fires are
halon still the best or are the conventional extinguishers just fine?

I've been told that it is extremely expensive to repair the damage if a
dry chemical extinguisher is used on a running engine. Even if nothing's
running, cleanup can be a big job. If the fire doesn't involve the plane,
a big dry chemical unit is far cheaper and easier to find than a Halon
unit. Even if it does involve the plane, dry chem is far better than no
extinguisher at all.

I keep a Halon unit in my aircraft. If I had a hangar, I would have a
fair sized dry chemical unit in the middle of each side wall.
