Stratosphere airplane from Airbus

Airbus has invented a support vehicle for a high-altitude airplane, particularly for stratosphere airplanes.

Climbing upto the height of stratosphere is very difficult for aiplanes. The plane needs greatest engine power for this ascent.
This new invention from Airbus structurally and functionally optimizes the operation of a high-altitude airplane both during its ascent into the stratosphere and during its operation in the stratosphere.

The support vehicle is arranged beneath the airplane allowing it to seperate from the high altitude airplane based on the force of gravity. It can rise up into stratosphere supporting the airplane to travel up to such height.
