The plane is flying over ninety thousand meters. That's 90km.
According to NASA, planes can't fly more than 12km (7.5miles). Even an experimental plane of NASA is only as high as 30km (19 miles).

If it's ninety thousand feet, that's still twice as today's commercial jets fly. The heighest was Concorde at 60 thousand feet.
