There was one British general that regularly used one for his transportation in Normandy. Of course it had RAF markings. I don't know if that reflected his confidence in Allied control of AAA or a very negative opinion of their accuracy.
Patton's men misidentified a British Auster as a Storch and opened up on it. But the general's driver IDed the aircraft and got them to stop shooting. That was fortunate, because the pilot was James Doohan, and there was no one to beam him up.
