The Me-264 could reach New York City. http://en.wikipedia.org/wiki/Messerschmitt_Me_264
The Me-264 had a range of 9,500 miles.
I used google earth to map the distance from the following:
Quimper, France: 3,376 miles
Brest, France: 3,350 miles
I don't know if they could carry a payload and make it that far or not.
I also don't know if the two above cities in France even have an air field. I figure that was minor they are easy enough to build. I just picked those places b/c they seem to be larger cities that were "close."
