Thankfully, the aircraft landed safely and let us hope the IAA and the FAA/NTSB conduct a full investigation for the cause of the incident.
Tom,
sorry to be pedantic, surely it would be the AAIU rather than IAA that would investigate.
As for ever finding out what cargo was on board, well, neither the Gardai nor Revenue have used their powers to inspect certain aircraft transiting Irish airports of late, so I doubt this will be any different.
I recall, not so very long ago, watching two World MD-11's, all window blinds down, land and taxi to remote stands in EIDW complete with Garda escort. No one got on, or off, they refuled and departed.
The state has a policy of "we have been told the aircraft are OK, so we won't look".
