A pretty weak connection. Also, keep in mind that the very late war
projects were largely make work and fantasy fuel for the Furher rather
than anything that could be promptly realized. In the case of a ramjet
mount on the X-15, the lower fin would have been the only place it could
have been fitted, having nothing to do with anything the Germans did.
