Based on historical FAA performance on modernization, what makes anyone
think that ADS-B will be ready to be implemented by 2020 or even 2050?

The contract recently signed with ITT to implement ADS-B nationally
presumably contains a performance clause and penalty for failure to
meet milestone dates.

Plus the ITT contract would have much of the system (ground stuff) in
place circa 2013...plenty of time for inevitable delays.
