Some fun in Brasil

Sitting in a hotel in Rio, decided to look in on flight data for an upcoming flight from SDU to VCP. Normally around an hour total trip time. Here’s what I found…maybe a result of aberrant technical inputs but geez…maybe not?

If not, what a ride for those poor pax. Enjoy the rest of the week everyone!

Looks like it diverted back to the dept station but the FA software assumed it made it back after it dropped off tracking.
