Hmm, reading Peter's post above dissecting the time order of the wording, I
guess I would want a clarification before renting. It looks to me as though
it was written so that a renter rolling the dice by flying away from the
homebase with a known problem would be responsible. Peter is right though,
if a pilot returned from lunch at a distant airport and found fuel running
out of the wings, the wording could be used to hold him to the rest of it.

If the "being flown" in the first line was replace by "departing the home
base" or "accepting the aircraft for flight" I would consider it reasonable.
