Niente panico ma è correto informare che solo gli aerei militari( non ricordo i modelli) hanno la compesazione volumetrica nel svutamento dei serbatoi  con gas inerte ( azoto?) per neutralizzare la formazione di miscele potenzialmente esplosive.
Per le aereomobili civili costerebbe troppo...........

The FAA has stated that there have been four fuel tank explosions in the previous 16 years—two on the ground, and two in the air—and that based on this statistic and on the FAA's estimate that one such explosion would happen every 60 million hours of flight time, about 9 such explosions will probably occur in the next 50 years. The inerting systems will probably prevent 8 of those 9 probable explosions, the FAA said. Before the inerting system rule was proposed, Boeing stated that it would install its own inerting system on airliners it manufactures beginning in 2005. Airbus had argued that its planes' electrical wiring made the inerting system an unnecessary expense.
