When I lived in Kenya I used to
live on the opposite side of Nairobi to Embakasi, the main airport at the time. On a quiet African night we could hear the East African VC-10s taking off for London at around 2300. I could never quite reconcile that volume of noise with the comparative hush in the cabin. Wasn't the advertising slogan something like "Swift, Silent , Serene"? Although maybe that was BOAC not EAA.
