Jumbo history!

The first jumbo jet carrying fare-paying passengers arrived at Heathrow airport on this day in 1970!!!
The then newly-constructed Boeing 747, Pan Am Flight Two, touched down at Heathrow at 1414GMT - seven hours late due to technical problems.
The jumbo had brought 324 passengers across the Atlantic from New York to London.
But the return journey to New York did not run so smoothly. Thirty-six of the 153 passengers transferred to other flights after a faulty compressed air bottle, used to blow open the plane's door in an emergency, meant take-off was delayed for four-and-a-half hours at Heathrow
