100kt down and 107 G/S means it was "flying" at 140KIAS, albeit at 60° AoA.
Gee Capn Bloggs, I'm a gurl and I can do math and estimate better than that. 100kt horizontal and 107kt vertical would be less than 45 degrees from horizontal by a small amount.
10912' per minute is 107.75305 knots if you work it out to an unwarranted degree of precision. So the velocity was about 151 knots at very nearly a 45° angle with horizontal.
(It's handy with tabbed browsers to keep
this link open when discussing this accident. It really helps avoid foot in mouth disease. It's not impossible, as I probably prove. But it does help. The other two good links are
