Caught the Titanic episode last night before the new episode, and since I’m not a Titanic/James Cameron fan, I thought it was okay. I did like the new episode- earth moving machines and explosions- what’s not to like. Even the small scale tests for waves in trenches were really cool.
As for using balloons as an airbag- not surprised by the result. However, in their control, the driver wearing a seatbelt wouldn’t have survived. I’m pretty certain seatbelts save lives at 35mph all the time, so I’m not sure how accurate their dropping a car from a crane really is.
