How did we get those? I tried google but probably am searching the wrong way.

Also, our intelligence gathering.

Very interesting article. Sonobuoys in WW2? Wow. (I used to work for GEC Marconi who made Sonobuoys on the same site - in fact most of our team had Sonobuoy experience https://www.dst.defence.gov.au/news/202 ... -subs-hide).
