I'm reading "The Blue Arena" written by Bob Spurdle, a New Zealand fighter pilot during WW2.
In the book he describes being on a low level anti-flak sweep over Holland in 1945 when a "cloud of rockets trailing steel cables leapt skywards from the trees"
I've never read anything else about a rocket AA weapon being used in WW2. Can anyone else shed any light on this?
I didn't find the right solution from the Internet.
