I hate posts like this it makes me look like a foamer. I has anybody heard anything about SIA 318 tonight. According to Flightaware it spent a bit of time at Lambourne, came into land on 09R, then flew around to land on 09R at the second attempt see:
FlightAware > Singapore Airlines (SQ) #318 Flight Tracker
This may be an error in Flightaware’s tracking software, it isn’t 100% 100% of the time. I understand these types of incidents are perfectly safe and all crews prepare for things like this but they don’t happen that frequently at Heathrow and even less frequently with a A380
