Would be interesting how many other ones have been quietly barrel rolled somewhere out of sight of prying eyes.....
Yeah but, it does take a bit more than average skill to barrel roll an aircraft properly in the real world. The consequences of getting it wrong in a transport cat jet would be..... messy!
These are some photos of a biz jet that was rolled by a pilot who's imagination outweighed his flying ability ("Duh, it worked on MSflightsim").
Also worth noting, AirmanDave has resurrected a thread that's nearly 2 years old.
