Before any aviation history enthusiast out there goes but what about the Tupolev Tu-155?
On Thursday, this TNW reporter was present for the fourth in a series of test flights.
If using up the aircrafts full storage capacity of 24kg, it could stay up for 8 hours.

And, the lack of carbon dioxide emissions.
H2FLYs propulsion system consists of hydrogen storage, a 120kW fuel-cell energy converter, and an electrical engine.
All in all, this summer was H2FLYs eight flight test campaign.
Liquid hydrogen is more energy dense than its gaseous counterpart.
That means that it requires significantly lower tank weights and volume.
But perhaps more significantly, it unlocks a much greater range.
The next step from H2FLY will now be to scale the fuel-cell system to megawatt capacity.
The H2F-175 system will unlock not only longer range, but also altitudes of up to 27,000 feet.
As an engineer, I can say that a 40-seater hydrogen-powered plane is a question of money and time.
After that it becomes visionary, Kallo stated.
For Project HEAVEN, H2FLY has been working with Air Liquide.
The hydrogen itself arrived in Maribor by truck, following rigorous safety requirements from the Slovenian authorities.
Liquid hydrogen has the potential to be a gamechanger for commercial aviation.
