Hello, Elle!
Been raining here!
Yes, 22 is the one stumping me.
I'll find out tomorrow what it should be!
5a, Worthless could be "gimcrack".
Plane makers, I think, is "Mig", reverse it, and "crack" could be matal fatigue.
12a is "Listeria", threat to health.
List could be a "minute", "i" for one in "era".
I had never heard of 27, "Noyade", but Anne Bradford had!
Or "ramen", "coddling", or "metadata".
This setter had us working today!
