In the case of the JP's we had just flown Leeming - Aldergrove and were quite content to return as the weather was more than adequate for a VFR transit if necessary. In the other case the aircraft had been fully certified by the CAA and had just been modified with the addition of some military radio and navigation aids; again the weather was benign. In neither case would I have had any hesitation in declining to fly the aircraft if the weather conditions had been marginal. There are, however, occasions when the Aircraft Captain has to bite the bullet and say "No" - irrespective of the rank or status of the passengers.
