Air Force TDSP? OTS?

Has anybody heard about the air force tdsp program, i have seen the online brochure, but can't seem to get in contact with an air force recruiter. If you could just give me some information on applying, and some other details about the program.

Also, since this program involves going to ots after sophomore year, could somebody give me some details on what ots is? I know it is officer training, but just looker for some specifics about the training ie.. difficulty(have heard its tough).

Thanks

Also, if someone could give me a number to a recruiter that would be nice, i've called two different offices and have not gotten an answer or a reply.
