This question is pretty broad, and depends of what comes to your mind when you think about technology. Is it a high-tech computer? Well, Intel is trying to develop (or may have already developed) an eight-core processor. Is it a spaceship? NASA is created a prototype of the spaceship that will land on Mars. Is it a brand-new airplane? Boeing is trying to create a more fuel-efficient airplane, the Boeing 787.Technology is being constantly recreated. If you want to keep up with the technology, you might want to try the technology sections of Digg, Technoari, StumbleUpon, or Reddit, where the latest technology news on the web may be found.

Yes, of course the Boeing 787 can fly. It is an aircraft (airplane)!
Boeing 777
The 787 series
the Boeing 747 is bigger han the 787. The Boeing 747 can seat over 400 people, but the Boeing 787 can only seat about 300 passengers. The Boeing 747 is the second largest commercial airplane in the world. (the largest commercial airplane in the world is the airbus A380.)
A Boeing 787 airplane can travel at the top speed of mach 0.89! Mach 0.89=677 mph The Boeing 787 can reach the top speed of 677 miles per hour!
Yes, the Boeing 787 is very very fast! It can travel at the full maximum speed of 677 miles per hour and yes the Boeing 787 is an aircraft (also known as an airplane).
The average number of seats on the Boeing 787 is about 250
Boeing is not an airline. They don't have any 787's on order.
The 747 is much larger than the 787. The 747-400's maximum takeoff weight is 875,000 pounds. The 787- 800's maximum takeoff weight is 484,000 pounds.
Boeing 747 is easily the largest. The "Boeing 900" you refer to is probably the Boeing 737-900 series, which is a short-medium ranged airplane.
Both, the Boeing 777 and the Boeing 787 have extremely long range than any other airplanes. The Boeing 777 is very old and it been around much longer than the Boeing 787. The Boeing 777 can also carry more passengers than the Boeing 787 but the Boeing 787 is lighter, can take off faster and easier, can travel faster and has more longer range than the Boeing 777. The Boeing 777 is heavier than the Boeing 787. Size does not even matter but the altitude and the range! Top speed of the Boeing 777: 567 miles per hour Top speed of the Boeing 787: 677 miles per hour Maximum cruising altitude of the Boeing 777: 43, 400 ft Maximum cruising altitude of the Boeing 787: 45, 200 ft
Boeing is currently designing the 747-800, and is experimenting with several airplane models.
