Nick, of course the 777 is FBW. That's why I mentioned it and in this context it is worth to see that everyone survived in LHR. The ground was also a bit harder, he had it nearly to the runway.
As for stall characteristics of airliners you are wrong: You can stall every aircraft, be it in whatever configuration. The stall speed goes down with leading edge devices (LED) extended, that doesn't mean you cannot stall it.
Except an Airbus in normal law, where it's impossible (some French tried it in Habsheim).
If you speak of low speed, that is also relative. If you hear expert opinions about speeds, they may certainly confirm that this accident happened in low speed. In opposition to an aircraft stalling in the air and falling from the skies with high speeds or like an aircraft crashing in cruising configuration. Let me reassure you that this THY aircraft crash landed with relatively normal landing speed, around reference speed. The investigators will certainly confirm that as soon as they have the results.
