Helium is the chemical element as it is colorless, odorless, tasteless, non-toxic, inert, monatomic gas and it’s boiling point is lowest of all the element. It is the second lightest element. Here in this video you can see Giant Airship which is filled with Helium. -This is billed as the world’s largest aircraft and is names as “flying bum”. It has the bulbous front end and it rose slowly into the air this Wednesday from an airfield to 45 miles north of London.
Due to unspecified technical issue the test flight which was planned for Sunday was cancelled. This is designed to use less fuel than a plane but this carried heavier object than the airships. They says that it can travel upto 90 mph and stay aloft for up for two weeks.
This looks so amazing as it looks so big and seems like it is very difficult to carry but you can see how it is flying on the sky. In this video you can see the first take off of this airship. This is the world’s largest airship and it makes maiden flight in UK.
