Messerschmitts were not just seen over Malaya, but even reported during the battle of the Coral Sea, by a most experienced and competent senior american pilot Lt.Cmdr. Paul H. Ramsay, (Co. VF-2)
The Messerschmitt was in US identification manuals, thus influencing expectations of what you would see.
However, I must agree with Many, for one pilot to believe that a Battle is actually a Hs-126 is weird, but may happen, but for seven men to share the delusion is perverse. Confusing Hs-126 with Lysanders or Mureaux is understandable, but the Battle?
A short comment aimed mainly at Brian Cull, not related to the preceding discussion about events in France on May 14th 1940.
Prompted by the mentioning of Messerschmitts in Malaya.
Could it all be "friendly fire" incidents?
In researching the actions there, did you look into the possibility of the Messerschmitts actually being Hurricanes, (and for that matter, mistaking Ki-27 for "Zeroes" actually being Buffaloes?)
