No.
Yes, the space shuttle is larger than a 747 airplane. The space shuttle is about 184 feet long with a wingspan of 78 feet, while a 747 has a length of around 231 feet with a wingspan of approximately 211 feet.
By attaching it to the top of a modified Boeing 747.
The Airbus A380 is not the only Rival for the Boeing 747.
depends what airbus.
The space shuttle is bolted to the top of the 747 carrying it with extremely heavy duty bolts. The pilots of the 747 also have to fly lower and at a reduced speed in order to keep everything in place. While a typical 747 can reach speeds of about 570 mph, a 747 with a shuttle attached can only reach half that speed if everything is to run smoothly.
The space shuttle is picked up with a hydraulic lifting crane the cradles it from both sides as it is lifted up and placed atop a specially modified 747. I wish I could provide a video for you but I can't find one. Here is the video link: http://www.space.com/15214-space-shuttle-ferry-era-final-flights-video.html
The Airbus A 380 was made by airbus to compete with the Boeing 747
A pair of 747 aircraft were specially modified to handle the shuttle orbiters. The orbiter is lifted by a crane and mounted to the back of the 747 using the same mount points the orbiter is mounted to the external fuel tank for launch. Upon arriving at the Kennedy Space Center, a similar crane lifts the orbiter off the 747 which then backs out from under the orbiter.
The first Shuttle that flew was piggy backed on top of a modified 747 and it's name was Enterprise. The first shuttle launched was Columbia.
They have a few Airbus A320 NEO's on order, but no signs of a 747. They are getting 777-300ER's though
The shuttle program has ended. So unless it flys over on the back of the 747 transport, never.
