One of the very odd characteristics of David Kelly's diaries as put into the public domain at the Hutton Inquiry is that they cannot be used (or were not used) as I use(d) a diary.
There is no sense of David Kelly using those diaries for forward planning.
Information, for example, about a flight is limited to date, destination and flight number (on those occasions when the data is fairly full).
Surely he would also need to know what time the flight was due to depart.
What did he use for such basic forward planning?
There is nothing in the diaries to record something like "On 8th to 10th September I am due to attend a conference at [some institution]".
How did David Kelly forward plan?
There is no evidence, for example, of him using a succesion of Post-it-type notes inside his diary to allow for multiple changes in plan.
Given the need in his professional life to adapt to circumstances he must have had some record of his existing commitments over the following weeks and months.
He must have had some form of planner diary. Where is it?
Is there another set of diaries that have been carefully concealed from public view?
