When we were kids airplane was 1/100 of how many they are now, but more than that they were around 80 tons and barely climbing... now they are 300 tons... 2 x the speed, 10 x the trust... air react differently to that. When you see a trial, make some elementary math about how many tons of liquid are you watching... an airplane cant carry that... 8) Thanks for attention and answer mate 8)
