As much as I agree with what twotters is saying, I still believe that a crook will do anything to achieve his crooked ways.
Example: then pres GMA approved the multi-million $ upgrading of the Manila enroute radar system. At the bidding, the project was awarded to a company from the Czech republic beating renowned and respected ATC systems manufacturers such as Thales, Eurocat, etc. Ok, nothing fishy in there I guess.
Three months after the Czech company installed the equipment, the ATCs are still using the old one as there are alot of glitches and incompatibility on the new system. They later found out that the company specializes on terminal/approach radar system and not for enroute. The ATCs as usual will be the ones to adjust.
Words have it that some consultants benefited (commission, I guess) on the deal. And we are talking big bucks in here, and not just a few thousand pesos slid under the table.
