any one individual controller. no swapping of shifts. managers will now be on duty during the late night and early a.m.s, and there is also a new hand-off procedure between the regional radar control and the local control tower. but but change that the f.a.a. did not make, shep, they are not going to allow, as you just suggested, for sanctioned napping for those controllers on the overnight shift. >> shepard: they wanted sanctioned napping like at times when jets weren't landing or something? >> exactly. that's what they wanted. we have spoken to one nationally recognized sleep expert who said you really should provide this kind of thing. he called these changes as they are presently constructed woefully inadequate. >> taking a nap in the middle of the shift, even for a short period of time will help promote enough alertness to keep them going throughout the rest of the shift. >> that option, obviously a no starter for the f.a.a. big wigs. here they are.
