A MASSIVE well done to the Kenn Borek Air crews, both air and ground for a successful mission. My curious mind wishes to ask a perhaps distasteful question, regarding money. The costs of sending several aircraft and crew on a 20,000mile round trip must be somewhat expensive, what would a ball-park figure be for such an endeavour ? I realise that the costs are covered by insurance/tax-payer dollars, but all the same..
