I just want to point your attention to this website - unfortunately in German - telling the history of Fliegerhorst Tulln-Langenlebarn close to Vienna:
http://www.gotech.at/lalemenue.html
Interesting pictures about Luftkriegsschule LKS 7 and its Flying Schools as well as a Ju 86 with an emblem unknown to me and a picture of a destroyed He 162M34 WNr 220022 (not 220092) are included. The loss of three He 162 is being described.
Sorry if you know this site already
Regards
