Excelent job!
Planes are design to belly land. Pilots, weather provided, they should land be as smooth as seen. Foam on the runway and  no fuel left on board the risk of fire should be limited to hydraulics and the little fuel left in tanks. An explosion, I imagine, may occur  if the fuel vapor left in the tanks ignite due to some internal spark or fire. Anyhow it seems that they dramatized too much the whole thing.
The big question is why the landing gear refuse to deploy. This incident must review the entire system.
These are just my thoughts.

But it also revealed that while the individual circuit-breaker for the alternate landing-gear extension motor was 'on', an overarching battery bus circuit-breaker - which protects several systems including the alternate landing-gear extension motor - was 'off'.

Polish investigation authority PKBWL said this 'off' position "was not recorded or indicated" either by the EICAS or the flight-data recorder of the 767.

Suspicion over the role of the circuit-breaker in the accident heightened during a test carried out as the aircraft was being recovered from the runway using cranes and air-bags.

After connecting a ground-power unit to the 767, and switching the battery bus circuit-breaker on, investigators successfully used the alternate landing-gear extension system to lower the undercarriage - enabling the aircraft to be towed to LOT's technical facilities.
