Just after 10am, traffic was at a standstill with lines several kilometres long heading towards the airport on Tonkin Highway and Great Eastern Highway as crowds flocked to the airport to try and catch a glimpse of the "giant of the skies".

Cars were reportedly backed up three to four kilometres with some people were seen sprinting along Tonkin Highway with their luggage in an attempt to catch their flights following the traffic chaos.

Dozens of motorists abandoned their cars on the side of Tonkin Highway and Great Eastern Highway heading towards the airport and were attempting to watch from the side of the road, or walking in and police were called in to try and contain the traffic chaos and move on anyone attempting to leave their car by the side of the road. Reporter Brendan Foster said the scene on Tonkin Highway this morning resembled a "Hollywood post-apocalyptic movie" where people left their cars and "gaze up to the sky waiting for a meteor to hit". The Antonov An-225 Mriya touches down in Perth. "I can't recall anything like it in Perth - ever! It's like the Woodstock of planes," he said.

However despite the traffic, the airport terminals were eerily empty with all the people at the airport there to watch the Antonov An-225 Mriya land, not catch a flight. Traffic was gridlocked around Perth Airport on Sunday morning.

"The level of public interest in the arrival of the Antonov is unprecedented, and Perth Airport worked closely with Antonov to ensure everyone who came to see the aircraft got a good view on Taxiway Charlie this morning.

"Never before has the An-225 made its way to Australia, and the people of Perth made the most of its visit today. We also welcomed media from all around Australia and some from other parts of the globe, who follow the Antonov on its travels," she said. The gigantic plane - loaded with its cargo, a 117-tonne generator purchased by a WA resources company, left Prague on Wednesday on its way to WA.

The last time a crowd that size flocked to the airport was in the 1980s when the Concorde supersonic airliner landed.

Aviation Association of WA president David Eyre said it may be the only time the six engine plane, which once transported a Russian space shuttle on its roof, travels to Australia. He said he knew of aviation enthusiasts travelling to Perth from across the country just to catch a glimpse of the 600-tonne aircraft. "It's a once in a lifetime opportunity for everybody so that's why everyone's so excited about it," Mr Eyre said. "It's planned at the moment it will come in from the north, but if the wind swings around on the day, it could come in from the south." DB Schenker, which specialises in handling challenging and difficult shipments for some of the world's largest resource projects, is coordinating the plane's arrival.

In a statement it said the plane would arrive in Perth after several refuelling stops en-route including Turkembashi, Hyderabad and Jakarta. The aircraft has a wing area twice the size of a Boeing 747 and must refuel every 4000 kilometres. "The Antonov 225 Mriya will remain for approximately two days in Perth departing on the 17th of May," the statement read. The Anotnov has 21 crew members comprised of seven cockpit crew, one flight manager, six engineers and additional support crew and will be in Perth for approximately 48 hours. The unloading of the aircraft will take up to 12 hours, and involves a sophisticated system of ramps and cranes to remove the cargo.
