Just last week I was telling a sweet young thing who was terrified of her first ever flight, which was to be on a CRJ, that although they have been flying for some years and there are 1000 or so around, they have never killed a passenger.
Inevitable that this state would change, but didn't expect it would be so soon.
BTW, before telling her that, looked at the accident database and found that indeed, although there have been several fatal crashes (including Pinnacle), no previous ones killed pax.
Initial reports suggest in flight explosion, but in circumstances like those of some previous accidents where ground observers misperceived breakup and associated fire on impact as a fireball before impact.
Don't know, given the host country, if we will get timely information re actual events. Did hear that Bombardier have despatched a team.
