the 8K barrier is just a mechanical barrier...plane are just not able to go upper it is all

and it is not 8K but 10K the limit with FMB

Yes and rpm at 2/3.
The real service celling of a Hurricane is 34.200 feet.
The Spitfire MK IA 31.900 feet the MK IIA 32.800 feet. Rate of climb initial 2530 feet/min. and 2600 feet/min respectively.
For the BF109 E-4 initial climb are 3.100 feet/min and service celling 36000 feet.
I do not know if all Hurricanes or Spitfire where capable of getting to this altitude? Planes are like cars some are faster than other for no special and objective reasons!
The fighting altitude over France in 1940 is 3000 meters, over the British isles it seems more 6000 meters. Naturalyy it depens of the target and type of plane!
