Quite a few people commented on last week’s strip that it’s not as impossible to track down ancient plane parts as we made it out to be in the comic. Well, that might be the case! It would not be the first time that we’d sacrifice historical or technical accuracy for a cheap laugh. But on the subject of today’s strip: Is there something like planned obsolescence in aviation? I’m sure the fastest moving sector is everything related to navigation, electronics, tablets and all that jazz. But I assume that most things in the industry are designed to be backwards compatible in all sorts of ways. Or am I being naive?
