El-Baz

The El-Baz was a type-15 shuttlepod attached to the USS Enterprise (NCC-1701-D).

In 2365, the El-Baz was discovered adrift with a duplicate Captain Jean-Luc Picard, having escaped the Enterprise's destruction several hours in the future to warn his past self. 

In 2370, when Guinan was about to meet her counterpart in an alternate timeline caused when Montgomery Scott traveled back in time to save James T. Kirk from the Nexus, Captain Picard recalled that meeting and wondered what the chronometric radiation readings might have been.
