Tragic though losses may be, that one should condemn the airplane as a result makes nearly as much sense as attempting to dehorn all the cows when the chicken coop burns down. It won't save the coop, and holds no logic.
I flew for the company that lost the coke execs, and can only say that those who know it all about that event probably don't, and shouldn't comment on it without ground upon which to stand.
I was also hired by the company in question to fly the subject airplane at one time, but will refrain from speculation or comment on this loss, presently. It's sad, it's unfortunate, and that's about all that should be said on the matter until real information is forthcoming.
As far as the airplane, and those that condemn it, a poor carpenter blames his tools. It's not the airplane. The airplane is what it is, and it's a known quantity. Those who elect to fly this airplane do so willingly, and knowingly, and trust in their ability to do so enough that they are willing to bet their life on the fact, just as we all do, every hour, every day.
A bet need not be a gamble; a prudent man bets only on a sure thing. Those who are not sure, then, gamble, and for this, there is loss. For the loss, we can only offer condolence, but in no wise should one condemn the airplane, for it's not the airplane. It's the pilot.
Always the pilot.
Any one who doesn't believe that in his heart has no place calling himself a pilot or taking the responsibility as pilot in command. Responsibility always rests with the pilot, and it's the pilot who pays for this responsibility, often with his certificate, often with his wallet, and forever with his life.
Today is no different.
