Agreed.
Many Luftwaffe airfields had "killing zones" of AA situated so that if you approached outside of the designated pattern, you had little chance of survival and if you did approach in the designated pattern but were not recognized/approved, you got shot up, too.
And their AA was layered (in different calibers) which meant that at tree-top or 10,000 feet, they were going to work you over.
