Sad this is. Any accident where lives are lost, is a tragedy, period. Lives are irreplaceable.
My thoughts to the families and friends of all involved. My best wishes and condolences, may all of us involved in aviation learn and grow safer allways.
One should focus to learn from such tragedies, support the people and companies involved and thus, make positive contributions.
This start off with training, with planning, contracts, maintenance, ATCs, airfield personnel, everybody, my wish it that all will work together in a supportive spirit to make flying the safe, fun and professional thing to do.
