I tend to distrust anything that the female of the species say about aircraft or car type recognition.
On the other hand, some have an uncanny ability to recognise, from a distance at whch males would barely even see, let alone recognise, any minor celebrity. They can also describe colours way beyond the range of primary colours that we males see. I don't even know what 'lilac' or 'peach' colour is, although admittedly being partly colour blind doesn't help.
A (female) friend of mine recently flew from CPT to LHR on an aircraft that, in her words: "only had two propellers, but I thought all the big ones had four."
