I swear I thought it started with an E or a I sound......any ideas?

Elevon.

For delta-wing vehicles, the ailerons (flaps on an airplane wing) and the elevators (flaps on the horizontal tail) are all on the trailing edge of the wing.

Elevon troubles could also result from a thermal failure -- burning wires, perhaps -- or there may have been a hardware failure in the elevon actuators.

That's the part they were referring to.....at the very back, behind the wings?

The guy on CNN said they were burning the midnight oil, zeroing in on that section maybe. CAUTION: I am not up on the technical terms, but I believe this is what he was pointing to.
