F 22 Raptor - The Biggest Waste?

OK – the F-22 Raptor fighter production has come to an end. Granted, we spent billions to design, test, and go into production and who cares about the loss of jobs that relate to the commitment. You can take a position on either side of the argument and probably make it sound convincing.
I have 2 questions.
1. When we began the spending on the project, at what point did it become too costly to continue? I find it hard to believe that it wasn’t an issue until they started in production.
Obama said he is “grateful” to members of the Senate who voted to end production of the F-22. “At a time when we’re fighting two wars and facing a serious deficit, this would have been an inexcusable waste of money,” Obama said at the White House. – Bloomberg.com

This brings us to question #2.
2. Why hasn’t the new Presidential Helicopter program been scrapped? I have read recent articles that give the cost of the president’s new helicopter.
When working on Sunrise Fire Department, we had the job of standing by for the landing of Presidential Helicopters. Did you notice the plural in helicopters? When the President flies he always flies in groups of 3 for security reasons. The Federal government can not be making 1 helicopter as that would stand out like a sore thumb. As it turns out, it appears that there will be 6 new copters being constructed – “at a time when we’re fighting 2 wars and facing a serious deficit, this would have been an inexcusable waste of money”.
I guess tax payers money is only wasted when it pertains to national security, certainly not the president’s comfort zone.
