Where are all the collectables?
The collectables are all either hidden somewhere on the level, likely near the ground between buildings or under a bridge, or attached to an enemy plane you must shoot down to catch it. Check for the number of collectables before you enter a map, either zero, one, or two. If there are two, then one will be attached to an enemy plane, and you’ll see it floating above that plane just like the RAF roundel does.
