A British Airways flight had to turn around more than eight hours after it left Heathrow in the early hours of Wednesday due to a ‘technical issue’.
The flight was carrying freight, according to British Airways, and had been suffering from a “minor technical issue”.
Flight data shows the Boeing-777 was cruising at more than 30,000ft when it encountered problems at around 7pm.
The flight was due to land at Sao Paulo Guarulhos International Airport at 23.45 UTC but never reached its final destination.
A British Airways spokesperson told Metro.co.uk: “Safety is always our priority, and after an indication of a minor technical issue our experienced pilots made the decision to return the freighter service to Heathrow as a precaution.”
The aircraft in question makes the UK to Brazil journey regularly, most recently on June 27.
In the last week the same plane had also completed trips from London to New York and Singapore, according to flight data.
