Recently Hans Jucker did send me the following e-mail:

Dear Arthur, 

you can do me a favour, if you bring the attached JU88 file on your website it would be fine, if you could post it close to the Lichtenstein paper. The reason for my request I’m tired to answer the many inquires from German guys for information about the JU 88 crew thus escaping imprisonment, just before the capitulation. The Germans told me that they have found the Lichtenstein paper on your website, but it seems for me they are more interested for action stories than for technical details.
