FYI: something that gets missed also.. 10-50K years of drift between NA and Europe needs to be subtracted. (as little as 2" to as much as 50"/year)
More likely the lower sea level is the enabler here..
Most of the continental shelf would be dry land, extending the coast by several hundred miles..
On both the American side and the European side..
The combined distances could reduce the trans oceanic distance by as much as 1000 miles..
Add to that the possibility that seasonal winds blew from europe to america, and you have a viable scenario..
