mr. marcus watkins, the director of the joint agency satellite division at nasa. our final witness is mr. david a. powner, the director of information technology management issues for the gao. and i thank you all for being here. as our witnesses should know, spoken testimony is limited to five minutes each, after which members of the committee have five minutes each to ask questions. your written testimony would be included in the record of the hearing. because of the importance and the complexity of the issues before us today, i will allow you to go over five minutes if you need to, if you can, make it within five minutes, please do so. i'm very proud memphis colleagues for keeping theirs under five minutes. i was slightly over, i think. is the practices of the subcommittee on investigations and oversight to receive testimony under oath. and we will use that practice today as well. do any of you have an objection to taking an oath? okay. let the record reflect that the witnesses were all willing to take the oath by saying no and shaking their head from side to sid
