1979, AA DC-10, ORD.
Slats in this case, not flaps.
Uncommanded slat retraction on the left wing after number one engine detatched at/just after rotation.
Very bad results.
Best option?
Airspeed, and plenty of it, obtained by level acceleration, if need be.
PS:
Keep in mind that if the DC-10 in question had been an L1011, the left wing slats would absolutely have not retracted uncommanded...IE: it is not possible, as the TriStar uses jackscrews for slat operation.
A far superior design, just like the rest of the aeroplane.
Ahhh, Lockheed
Simply built to a higher standard.
