Keep in mind the Sunderland (after Mark III) had a range of over 3000 miles, and the Wellington of at least 2200 miles. They flew not just out of GB, but also Canada, Greenland, IceLand, the Azores. GB also got a bunch of lend-lease B17's which they used for Atlantic Patrols.
The Atlantic "gap" was something the Allies rushed to plug up - with long range patrol aircraft (Sunderlands, PBY's, Wellingtons, and so forth) and by building airstrips on any available Island.
So, depending on where you are in the war - yes, aircraft can hit you, and did. Sunderlands, PBY's, etc ranged thousands of miles out from their bases. Escort carriers helped to plug the air-gap, but it was mainly long range, land based planes that closed the mid-Atlantic.
Google for "Battle of the ATlantic" and "Air Gap" - there's lots of info out there.
