The pilot flying realised at that point they were at 38,000 feet and queried the pilot not flying whether they weren't assigned to FL350
BOAC : you are right but they got what they asked for :
1) PNF presses autopilot disconnect
2) PNF pull stick back 75% for 6 seconds
3) a/c climbs with 2000ft/min initially then pitch increases to 12 degr up and the vertical speed increases through 5700 feet per minute,
This not automation / Airbus computer logic that put the aircraft at 38.000 ft at Mach .66 with 12 degr nose up...
