Hello,
I did have look at this map:
http://www.mapywig.org/m/German_maps...w_III.1941.jpg
And I did see there place (actually at least two of them - one north of Dno, another east of Dno) named Kriwucha. One can easily read this one as Krussicha if he/she separates vertical lines in letters iwu differently.
Also on map there are places Drosdicha and Krasucha - plenty of possibilites to speak and write them wrong
I was also contacted off the forum and suggested that maybe Dno-Grivochki (5 km south of Dno) is place we are searching for. There was landing ground, some pictures here:
