Lufhansa Ju-52 and Boeing 737 in Formation Flight

A beautiful clip of a Lufthansa Boeing 737 and a Junkers Ju-52 flying formation above what I believe to be the Boston skyline. My Dad managed to get this little gem off the Lufthansa website years and years ago, where it, and a whole lot of other videos and pictures, sadly disappeared from. If anyone has any more info on this, I’m keen to hear it. Enjoy!
