The majestic Zeppelin is now the largest airship in the world.  It is 75 meters long.  Its cruising speed is about 100 km/h (maximum 125 km/h) and depends on the strength and direction of the wind.  Maximum flight altitude - 3000 m above sea level, normal cruising altitude about 300 m above the ground.  The Zeppelin uses non-flammable helium gas.
 
Tickets for flights are not available, they went to clients, guests, business partners.  You could also win them in a contest.  But it's worth watching out for the giant gliding majestically and silently over the cities in the sky.
