First of all, it has been over 20 years since I last flew so I am not a knowledgeable source for the size of prohibited airspace. There are other members much more current and knowledgeable than I am on these.
Taking your 30 mile diameter circle as given, it would depend on the exact model of the J3. J3's had different engines. But let's assume an "average" J3 speed of between 65 and 75 knots
To get to the center of your 30 mile circle (15 mile) would take about 12 minutes. A little less if the pilot is diving and has no intention of surviving.
The payload of the J3 is about 500 pounds. That's a lot of explosive that could be carried.
Not saying that a J3 is the uber weapon of choice, but I would hardly dismiss the threat of a J3 in the hands of a dedicated Bad Guy.
