Ri Ki Bong, chief of the panel for investigating the cause of explosion of the "joint investigation team", who attended the third meeting of the "ad hoc committee for probing the truth about the warship Cheonan case of the National Assembly" on June 11 said that only non-crystalline oxide aluminum was detected at the beginning of the survey and that crystalline oxide aluminum was not discovered at that time because its amount was too small to be detected. He admitted the errors made in the team's "results of investigation", mumbling that a tiny amount of crystalline oxide aluminum was discovered in the course of the additional investigation conducted later.

The "joint investigation team" is now talking nonsense that it confirmed that crystalline and non-crystalline oxide aluminum is simultaneously detected after the exploded powder has been reduced to ashes and in that case its amount is very tiny.

Hangyore said: After all, he tried to justify the "results of investigation" with absurd logic, ignorant of even the scientific fact that aluminum cannot change into non-crystalline oxide 100 percent.

The media verification committee for probing the truth about the warship "Cheonan" made up of media organizations said that the joint investigation team asserted that the results of the analysis of adsorbent were the most scientific evidence among the results of investigation presented by it. Now that the above-said results have been overturned, it is necessary to form a new investigation team with civilians and restart the investigation from the very beginning and, at the same time, conduct inspection of the state administration and a public hearing, etc. without fail if doubts about the overall investigation into the case are to be cleared.
