i am sure a few years back Airbus won the tanker contract with A330, but due to congress it was re-opened again
am i correct

The tanker contract is a can of worms best kept closed.

To give a very brief summary: we are now on the third incarnation of the tanker contract. Contract one was awarded to Boeing in 2002/2003, but following a corruption scandal the contract was cancelled in 2005.

The second contract went to EADS/Northrop in 2008. Barely half a year later the US Government Accountability Office cancelled the order. Boeing had filed a complaint and quite a few politicians and citizens complained that EADS was not sufficiently patriotic.

We are now in the third run of the contract. Already mistakes have been made that are dumb enough that when a decision is finally made the loosing party has sufficient grounds to throw a fit. Basically, due to a clerical blunder the Boeing bid was passed to EADS (now without Northrop) and the EADS bid to Boeing. A proposal by Antonov based on the An-112 (a proposed twin jet powered An-70 derivative) was handed half an hour or so too late after the courier got lost on the USAF base where he had to hand in the bidpack.
