stolen jet engine

Recently, malaysians are havoc with the news of the two missing jet engine.
This damn shocking, those engine was missing in 2007 and make public end of 2009.????
Those engines are big, it needs proper plan to carry it and ship it to the buyers.
And the price is rm50 millions ????
my theory of the missing engines.
1. They were sold/send Iran for the reverse engineering.
2. They were dissembled parts by parts, sold as spare part in ebay.
3. They taken by the Aliens.,(real alian not the PATI)
4. They were sold to Airasia for spare part.
5. They were sold to the antic collector.
