This is from a South African friend who is in the industry:
. Anecdotal info is that a fuel line fractured on the carburetor avgas radial left engine. Fire then burned through the oil lines. Loss of pressure prevented them from feathering the prop. They turned right downwind to avoid crashing into built up areas. I.e. Against the live engine. They set it down on base but hit a single story steel and brick warehouse tearing chunks out and bending the i beams at right angles. Probably with an engine. This effectively broke their speed. Landed straight ahead with both wings separating and burning. All 18 pax WALKED OUT! Pilots injured but not sure how badly.
