Firstly they let the Press look around their Brand New Terminal 5 Building
Link Comment elsewhere .Which I broadly agree with.
"Its a Glorified Expensive Shopping mall with Waiting room" and there are Now 5 on the Site

Who in their right Mind is going to pay Inflated prices for a "Taste of Britain?"
NOTE T5 is For BA flights only!So the Majority of "customers" are British Subject who are aware of this Rip-off

And of course in the Afternoon this happened to a BA Flight from China Nobody hurt, few people shook up

Trivia: Thursday's crash is the first on either landing or takeoff at Heathrow since 1972
My comment:
You can't trust those Figures
Plane movements are a takeoff or landing every few minutes.
And, They are asking for another Runway to the North to Cope with "Increasing Traffic".That is a Frightening prospect! 
Moral: If you are Travelling to and from the UK use one of the regional Airports Or even Dublin Airport
Avoid Heathrow like the Plague! May cost extra in travel time and costs but you'll feel safer
