We’ve been doing this comic for long enough now to know exactly what kind of feedback we would be getting for this particular strip. So, let us come out up-front with an explanation: Yes, we know that most aircraft have circuit breakers installed and not old fashioned glass fuses (or whatever you call those type of fuses with a melting wire in English). But the Roost Air Cessna is very old, and also has a lot of custom modifications installed by Julio. There you go! :-)
