Final answer:
No, the plane did not make its first contact with the Earth when it hit the lake. The Huygens probe landed on the surface of Titan, a moon of Saturn, which is composed of water ice like rock.
Step-by-step explanation:
No, the plane did not make its first contact with the Earth when it hit the lake. In the context of the question, the Huygens probe was mentioned, which is actually a probe that was sent to Titan, one of Saturn's moons. The probe landed on the surface of Titan, which is composed of water ice, similar to rock. So, the probe made its first contact with the surface of Titan, not the Earth.
