What if your will EXPLICITLY request that your remains be recovered at ALL cost for full military honors. Would the Navy deny a possible salvage/recovery mission?
Good one.
Your will decides who gets your shit.
(Actually, the PERE [person eligible to receive effects] as designated on your Page 2 says who gets your shit, if someone disputes that then the civil court system breaks out the will)
Navy policy decides what gets recovered and what doesn't. The Navy considers aircraft and ships to be appropriate final resting places for sailors.
If someone does not like the sound of that, there is always the army.
