Very sad case indeed.
Yes I am aware the accident report is not yet out on this one.
However the CL wing does seem a very unforgiving and particularly vicious wing when contaminated near the stall. What a great shame the manufacturers and authorities are unable to come up with a realistic test to see how an a/c performs at Vr+ with contaminated wings. In actual fact, any pilot of any a/c, who attempts to get airborne with contaminated flying surfaces becomes part of the test flight program.
