On August 1st, a British Airways Airbus A380 flying from Johannesburg OR Tambo International in South Africa to London Heathrow was forced to return to its point of origin due to reports of smoke in the cabin. It was later revealed that the problem even affected the jet’s crew rest area.
The issue forced the double-decker quadjet to return to Johannesburg. Because it didn’t perform a fuel dump, the landing was fairly heavy.
