A group representing relatives of those who died in the Tuskar air crash is to disband following yesterday's report despite acknowledging that questions remain.
The Tuskar Tragedy Relatives Support Group said they were satisfied the investigators had gone as far as they could in solving the mystery and the group could do no more.
Speaking after a 2½-hour presentation by the investigators, a spokeswoman, Mrs Celine O'Donoghue said: "I am satisfied in so far as what they showed us was very logical and very thorough. They did a superb job.
"You would have to ask the question why, after two years, we found out there were missing maintenance files and after another two years we find out there was a different flight path to the one believed.
"The more you look, the more you find.
"But I don't think anybody went in with the expectation of finding out for certain what happened.
"All we expected was to find out what was the most likely cause and we've been told that. Individually some relatives may pursue it further but as a group we've done all we can."
Mr David O'Beirne, son of Capt Barney O'Beirne, learned for the first time from the report of the valiant efforts his father and co-pilot made to bring the stricken aircraft under control.
"They recovered it from two near-fatal spins which we didn't know before. It shows the level of professionalism and inner strength they displayed."
Mr O'Beirne also praised the investigators for their thoroughness.
"I did hope that by some miracle they would have been able to take it a step a further, and we continue to live in hope, but what we have achieved as a group and what they achieved in their investigation has been exemplary.
"They have unravelled the mystery and brought us closer to probable cause than ever before.
A lot of people will be able to accept that. I will have to give it some thought, but there is a large amount of closure in it; maybe not final closure but a step in the right direction."
