Well then we can just have Jason give a general departure broadcast like :
" Cargo Boat Destiny, departing Greenleaf Atmo (give the time), preparing for max burn."
Then give'r hell and lets scoot.
That should sound normal and we're off! That won't look like we hiding anything and should not raise suspicions.
It's only being polite on popular planet were the rich and famous come to play.
Went ahead and posted, one way or the other it should stir up some action.
