Airspeedintervention, your concern about having experienced a possible nav error and expressing that concern here then posting again having learned of the Resolute Bay tragedy, is commendable. The explanation given by other posters of the seeming discrepancy is probably correct, but so was your willingness to put your concern to your peers. One day that willingness could save lives, never lose it!
