I thought I get an opinion from the peanut gallery about a situation I had as a passenger. I won't give out what airline but it was a CRJ. The aircraft arrived about 1 hour prior to the departure and there was a crew swap. It was raining out. The next crew was delayed and arrived at the aircraft about 15 minutes after scheduled departure and found a tire that needed to be replaced. Now my question comes that had the previous crew done post flight walk around wouldn't they have found a tire that was bad enough that it needed to be replaced? I have a few thousand hours in the CRJ and wasn't very happy this was left to the next crew as my experience is that bad tires are obvious. Post flight should be as thorough as pre-flight, aren't we are all on the same team?
