Amendments to the Report

CONCLUSION

From the hypotheses listed in paragraph 14.4 and discussed in sub-paragraphs

14.4.1
14.4.2.1
14.4.2.2
14.4.2.3
14.4.2.4
14.4.2.5
14.4.2.6

The Board, having found in the facts under examination no significant and concrete indication or evidence that would warrant suggesting as the probable cause one or more of the hypotheses discussed in sub-paragraphs

14.4.1
14.4.2.1
14.4.2.2
14.4.2.3
14.4.2.4
14.4.2.5

points to the hypothesis dealt with in par. 14.4.2.6, namely

Explosion set off by static-electricity discharges (streamer corona)

as the probable cause of the accident.

(3) CHAPTER XVI

Remains as it now appears in the Report, except for the elimination of the last paragraph.

Elimination of the last paragraph is necessary, according to strict logic, on the basis of the following line of reasoning.

A hypothesis may be

(a) Impossible

(b) Possible (insofar as there are no elements that justify classifying it as probable)

(c) Possible and probable (if there are elements that justify classifying it as probable)

All seven hypotheses discussed in the Report are possible and, as such, each one of them could have actually occurred.

Of these seven hypotheses, the first six are possible, but the inquiry has brought out no evidence or indication suggesting that any of them is probable.
