Agreed, ditto.
The list of aviation recipients of the Bavarian Knight's Cross of the Military Max-Joseph Order is a pretty brief (and selective) group. This comes from Neal O'Connor's Volume 1:
Ltn. Walter Ritter von Lichtenberger - Sept. 9,1915
Ltn. Maximilian Ritter von Mulzer - July 8, 1916
Ltn.
Hans Ritter von Adam - July 28, 1917
Oblt.
Eduard Ritter von Dostler - Aug. 18, 1917
Oblt. Friedrich Ritter von Krauser - Sept. 20, 1917
Ltn. Max Ritter von Müller - Nov. 11, 1917
Ltn. Friedrich Ritter von Röth - Jan. 25, 1918
Oblt.
Eduard Ritter von Schleich - June 14, 1918
Ltn. Hermann Ritter von Lechner - Oct. 5, 1918
Oblt.
Robert Ritter von Greim - Oct. 23, 1918
Ltn. Georg Ritter von Hengl - Oct. 29, 1918
At the time of writing his first volume, Neal noted that "None of the six Knight's Crosses given to non-Bavarians went to a flier. Three of those awards went to Prussian staff officers, two went to captains of successful naval surface raiders and one was given to a submarine commander."
Neal also noted that the Prussian command made application to the Bavarian Orders Chancery for
Manfred von Richthofen to be awarded the "Max-Joseph" on 6 May 1917, but this was turned down as he was not Bavarian. Also -
Ernst Udet, though born in Frankfurt-am-Main, had lived in Munich since his family had moved there when he was a child. Somewhat nominally a Bavarian, Udet was nonetheless never awarded the Max-Joseph even though he lobbied for it after the war. He had never flown in a Bavarian formation, either...
