Jet Airways B777-300 descends 5000 feet uncontrolled.
 

First Officer using her tablet did not notice the plane leaving its assigned level of 34,000 feet and descended to 29,000. :ugh:

The captain was asleep taking ":controlled rest".

This incident occurred on 18th August and is reported here:

Already discussed on SE Asia forum

Did it plunge or plummet ?

August 8th, not 18th.
