Fifty years ago today, the first jumbo jet in the world carried passengers from New York to Heathrow Airport.
The Boeing 747 brought mass travel to millions as it was bigger therefore carried more passengers, making air travel more affordable.
Alan Temple from Buckinghamshire was there on that day in 1970.
At the age of 76, he still works at the airport.
The airline was Pan Am, later taken over by United Airlines.
Former Pan Am staff and others who spent many years on the jumbo jet remember the so-called 'golden era'.
However 50 years on, the plane they call the 'Queen of the Skies' is slowly being retired by airlines around the world and replaced with new, greener, more fuel efficient planes.
