Today's GPS Satellite Launch Scrubbed

Silly question - shouldn't a "planned hold" just be planned into the timeline? If a 10-minute hold is planned at T -4, it's not really T -4, is it?

It works the same as the "Manned Launches". The computers all know what has to be done from T -4 to Liftoff... The final 10 minute holds are for the people (launch Controllers) to make sure all is ready (fuel, electric, computers etc.) before turning it loose LOL

 

The manned holds are at T -9 But they actually have 3 - 4 Built-in Holds from 3 days before launch to liftoff....
