thats amazing. i cant believe they were able to 'buzz the tower' like that. could they swing that sport with nothing more than a rig and a car (no plane)?
i dont remember those suits getting a glide rate like that. after some quick googling i found this

"glide ratios of 2.5:1 are commonplace" that is crazy!!
