1.   Cables that carry fluids did not perform as engineers had hoped, or expected.

2.   Engineers hope that, at the earliest, renewed efforts to remove the obstacle could be successful late Saturday or on Sunday.

3.   Engineers hope the modification will prevent fuel tank punctures, which officials suspect caused the Air France crash in July.

4.   Engineers hope to build this into future generations of robots.

5.   Engineers hope the insulation moderates temperature extremes that may cause unusual power variations, and occasional stalls, seen in the motors when they move the solar arrays.

6.   Some engineers hoped Condit, who once worked as a Boeing engineer, would play the same role in their negotiations.

7.   Space agency engineers hope the experiment proves the feasibility of launching spacecraft with inflatable antennas or other major parts.

8.   The engineers hope a method they worked out to warm the engines before firing will solve the problem.

9.   The plane will be on the ground, but engineers hope to make flight conditions as realistic as possible.

10.   Engineers had hoped to find the problem then.
