Assuming that the cabin crew started heating food as soon as possible after takeoff, 25 minutes into the flight could conceivably be the time it takes for the food heaters to reach high temperature. One (or more) of those food packages could have been a bomb - disguised as a meal (breakfast?) – detonated by being heated to a moderately high temperature.
Not bad.
But still I have no clear signal that bomb IS located. All investigation and security activity we are aware of just shows us that any other version was weighted and found less possible...
