from what I hear from a CRJ pilot I know, his AOM/POH charts show that a max gross CRJ-100 needs 4800 feet to clear a 50ft obstacle with zero wind.
assuming the wind was as stated [220/10] there would be a zero headwind component to a Rwy 26 departure.
There was no windshear alert and no new Metar published at the time of the crash - routine weather reporting, not even a SPEC. If the wind changed due to a wind shift [expected with a WS alert] there would have been a new metar and a WS added to the metar.
This one seems like taking off on the wrong runway.
The tower guys know- they would have cleared the airplane to depart 26 or 22 and the tapes will not lie. Moreover, 26 is not permitted at night to part 121/135 operators - no lights. Notam states MIRL 08/26 OTS INDEF. Sunrise today was 7.05a, they departed 6.07a.
Technically they flew in daylight for the purposes of pilot currency [not required for part 121 or 135 ops anyway] but it was still night for the purpose of operating at a towered field, which is 30 minutes before/after sunrise.
I’m sure they could see the runway in the twilight [with clouds though that might be in doubt] but with a lighted one right next to it - it makes you wonder.
My wonder is about crew rest, what was their day like yesterday, with a 6a depart you wonder if they got in late last night and got the full measure of real rest. Thats the kind of mistake a tired crew would make . …
