Not at all ... if the witness says she saw long sleeves that is fine.
If the other two witnesses whose statements we have seen didn't that is fine also.
It should be borne in mind that witness number one couldn't remember which day it was that she took the flight home.
The long sleevesOne of three things in my opinion:
1) It wasn't Madeleine
2) It was Madeleine, but she was shivering and maybe turning blue, so she was taken somewhere en route and they "borrowed" a long sleeved top for her. I have always wonderd if the time differences between the Jane Tanner sighting and the Smith sighting meant that she had been taken somewhere en route?
I wondered about the "Staff Quarters".
They are just up the road from the Smith sighting, according to someone on the 3A's a scream was heard coming from somewhere there
.... and I have always felt that the lifting of Madeleine, from her bed, would have been done by someone that she knew in case she woke up.
3) that the witness was mistaken about the long sleeves. This seems the least likely to me.
