Another fire department of the Greater Polish Voivodeship confirms that the police asked the fire brigade to come to one of the enterprises in the Mountains to exclude "any possible threat". The burning elements of the Falcon 9 rocket flew over the early in the morning. Police can not determine the origin of the found subject at this time. However, one of the "space fragments" has not landed in the cockles. It is probably a tank.
Falcon 9 has a composite tank that is used to store high pressure helium. Helium is used to maintain the required pressure in the fuel tanks while operating engines, preventing their destruction and ensuring a constant flow of fuel. These tanks are made of light metal core wrapped in carbon fibers, which provides high strength in low weight. After Falcon 9 explosion in 2016, caused by tanks, SpaceX improved the structure, increasing the safety and reliability of the entire system.
