British Airways is set to become the first UK airline to take delivery of an Airbus A380 superjumbo - the world's largest passenger plane.
BA's first A380 is due to touch down at Heathrow, with the airline's chief executive Keith Williams on board.
The BA double-decker superjumbo will be shown off at the carrier's engineering base at Hatton Cross alongside another recently-delivered aircraft, a Boeing 787 Dreamliner.
This will be the first of 12 superjumbos ordered by BA, with passenger services due to start this autumn.
BA is configuring the massive, 238ft-long A380 to take 469 passengers, slightly fewer than some of the other superjumbo-operating airlines.
Those aboard the BA plane will be flying on an aircraft that is 79ft high, with wings that are 54% larger than those of the Boeing 747 jumbo jet.
The A380 also has 50% more floor space than the Boeing 747 yet is 50% quieter on take-off. Many who have travelled on the superjumbo have noticed how quieter it is on board, as well.
Powered by four Rolls-Royce Trent 900 engines, the A380 can reach a speed of 587mph and has a range of 9,500 miles. The surface of the superjumbo is covered in three layers of paint weighing around 500kg.
If all the wiring in the A380 is laid end to end it will stretch from Edinburgh to London.
The A380's arrival follows the delivery last week of the first two of BA's Dreamliners. A second superjumbo is due to arrive in September.
