ORAC, you seem to be suggesting that all parties to the contract were named in the DM
Now many many years ago there was anot dissimilar scam at Alor Star.
The plan was to increase the RW LCN to, IIRC, 20. Accordingly truck upon truck of hardcore was delivered to the base. What no one noticed was the hardcore was then trucked off the base only to return through the main gate shortly thereafter.
Only when a Valetta landed on and went through the runway was the scam discovered. The RW LCN was classed as 5.
