I think she's talking about the new TV show "Ex Wives Club" Two people each week meet up with Stalones ex, Federline and Trumps ex, Marla Maples. In the show these regular people tell their story of betrayal.

They tell how their marriage ended and the ladies put them through some workshops to get them back on their feet.
Part of the show includes saying good bye to the past and on one episode a womans ex's car was dropped out of an airplane to crash below, the revenge part.

I heard them interviewed on Larry King and that part wasn't real. It was just for TV shock value and was just a car that looked like her husbands. (she said he loved the car more than her)

I think the show is good as they help hurt people usually left by their spouse, often for another. The positive aspect of it is good but the revenge part is counter productive in my view.

The best revenge is personal success, letting go and moving on.
