Hello!
Please. Consider the geography also. Took a look of this map for example:

In my mind there is no doubt whatsoever that Leykauf did NOT claim his Boston over Baltic Sea. Gotska Sando is not near Tallinn for heaven's sake.
What is possible is that the 1 GvMTAP Boston was on one of the "standard" return routes from Baltic Sea which went over Bay of Riga towards East until over frontline and then back to home base. This would take the plane to the area near Pljussa. A PoW interrogation protocol explains these routes and this I have learned after my posting in Feb 2007 (#8).
In other words I find it now plausible that it indeed was 1 GvMTAP Boston. But the shoot-down location is over land, near Pljusssa.
Regards,
Kari
