I hate to say it guys, but the fact the airframes have been CRJ/Challenger tends towards smaller airlines, private charter and corporate work.
Case in point was the Birmingham UK Challenger crash about 5 years ago.
Skipper asked about deicing (heavy overnight hoar frost) ... when he got the price and queue time he decided he'd just go without !
On rotate, one wing stalled, the other continued to fly - cartwheel - fireball - 5 fatalities. I saw the pictures on the news - and I immediately recognised the burnt out frame of a CRJ/Challenger on its back with the gear sticking up ...
This appears to be becoming an all too 'common' problem with this airframe. Its a supercritical wing - if its not clean - don't fly !
