If it were OTS only, then it works for everyone. Applicants can go to a 4 yr school of their choice. Get a degree in whatever they like and still apply for atc. Worse case senario, if they are not selected, they still have their 4 yr degree in what ever career field they chose and can go on to pursue that or get their graduate degree.
This would eliminate the need for CTI (especially the poor kids that "major" in atc management) and cannot walk into an investment firm, construction company, or law enforcement office after graduation (because they're now waiting 2 years just to get selected) and get a job because their degree just so happens to be aviation specific.
Example: 4 of my CTI counter parts who've waitied after graduation in 09 didn't go right into "good paying jobs". Mind you, you only have 6 months to defer your student loans before they come hunting you down. Two worked at walmart, one throws bags at an airport for little more than $9/hr, the other (who has a family) couldn't find anything and now "volunteers" at an animail shelter, cleaning dog $*%! out of their cages. All of these have 4 yr atc degrees and all of em said at one point or the other that if they could've gotten a degree in another field, they would've.
Hence why I stated the the OTS only option. What benefit does cti really give you, a lil less time at the academy??? But still a hell of a wait just trying to get there. Either route, cti/ots still have to go to okc and learn the same $#!* in the same classes right next to each other.
