Police helicopter crashes onto Glasgow pub

[xlsky]

Probably more like an equal forward and vertical speed

in that case the heli must have been above the Clyde, to the South? Apparently he was last seen just North of the river and crash site, above the city; look in what direction the fuselage is facing. seems like loss of control to some serious degree, and clearly vertical descent, the roof looks die-cut. No shifted battens or crumbled sheets.
