About the only thing which might be capable of resurfacing after a trip to the bottom would be something in the fuel system which hadn't been ruptured by the impact. However. it's fairly unlikely that anything forming an envelope filled with fuel would survive an impact without damage to the seal integrity.
Although a vessel which is 100% liquid filled would not be crushed (as much) as the remainder of the debris, it would need to form an unbrella shape to trap the less dense & relatively incompressible fuel at the top of the shape & keep its centre of gravity below the centre of the volume of fuel (centre of bouyancy).
I watched what happened to the Bathyscaphe Trieste once when they left a valve open and it trapped about a cup full of air in one of the battery on-surface vent lines. The top of the battery compartment crushed in on top of the batteries shorting them out while on the bottom. A very bad thing to happen when your main means of ascent depends on the battery power.
Make a mistake like that and you remember it forever. So a little air in a tank is a very very bad thing in the very deep
