The track record for CDO's ("SDP's") in this industry is clear. Guys like them and bid them because it allows them to be home every day and do whatever it is they want/need to do. They do not sleep during the day. The only sleep they get is whatever sleep the CDO provides. There may be rare exceptions to that, but the track record is clear that the vast majority do exactly as I described. Operating a flight (whether it's a short flight or a long flight) on maybe 3 or 4 hours of sleep in a 24 hour period is UNSAFE. Period.

If we ever get these horrid things, I will not sign the release to operate that morning flight. If I can't avoid the trip, I'll be forced to call in fatigued for the morning flight. Do you really want to put Delta pilots in that position?
