According to the report, the investigation is looking into two possible explanations: either the plane was taken outside its flight envelope by human error, or the crash was caused by a technical issue with the steering or motor functions.
There were most likely between 10 and 20 seconds between the final output by the plane until it hit the ground. There was no attempt to abandon the plane.
While the investigation into the steering and motor systems has not yet been completed, it has so far found no evidence of technical issues with either system.
The report recommended that rigorous technical tests must be done to the "Snunit" (swallow) planes and their parts before they can be approved to return to regular flights.
Norkin said after receiving the report that he would bring the Snunit planes back gradually, for training flights, after tests were completed.
