Blade - I wasn't there and neither were you. I don't know whether they were in a position to put it in the river 'right side up at 120 kts with full flap' and neither do you. I humbly suggest you wait until the accident investigation is completed before making such assumptions.
Oh, and by the way, if you care to check you'll find the river is more or less perpendicular to the runway straight after take-off. Your assertion that their take-off path was 'along a big wide river' is somewhat short of the truth.
