very often, you might have a computer program and it has flight plans on it. You tend to keep old flight plans so that if you do the same flight or similar, its just a case of filling in a few details and times etc. You fill in a box with the name of the pilot. Maybe he just neglected to change it. Maybe it was a rush job at the time and he didn't notice. Maybe he asked DH to fill the FP in for him?? We don't know any of the real facts as yet so better not to speculate too much. Speculation is fair and reasonable if reigned in, but starting to say things like using another identity? Maybe not the right thing to be posting.
