I want to know the answer to the following question:
What force used Sunderland flying boats out of Devonport?
All the background I'm provided with is that "This was largely due to Plymouth's status as a major port Charles Church was hit by incendiary bombs and partially destroyed in 1941 during the Blitz, but has not been demolished, as it is now an official permanent monument to the bombing of Plymouth during World War II.". Is that enough to answer the question?
Answer: no
