I think there is confusion about reconnaissance flights carried out by the Ar 234. In particular the flights over Normandy by Erich Sommer. I read one account where it was made clear that this aircraft could not be intercepted, including by the Mosquito. I recall seeing one original document on ebay where the two cameras that were installed were mentioned. And there is this book: Hitler's Spyplane over Normandy 1944: The World's First Jet.
There was a reconnaissance flight carried out by an Ar 234 over Scotland on April 10, 1945. Source:
