Well looks like a terrible mistake if he took off on 26 instead of 22:
CRJ200 ER
FAR take-off field length (SL, ISA) at MTOW 5,800 ft 1,768 m
FAR 121 landing field length (SL) at MLW 4,850 ft 1,479 m

CRJ200 LR
FAR take-off field length (SL, ISA) at MTOW 6,290 ft 1,918 m
FAR landing field length (SL) at MLW 4,850 ft 1,479 m

I strongly suspect that 6,290 figure is the length of runway for the
plane to accelerate to V1, take a engine cut, and stop on the runway
using only brakes, with no credit for reverse thrust. The distance for
a nominal takeoff roll is much shorter.

So sad . . . my prayers for the families of the folks on board,
passengers and crew.
