SkyCats are inherently safe and tolerant to hazard. Key points to note are:
Lift gas: the lift gas (helium) is not merely inert but acts as a fire extinguisher.
Structural safety: the natural buoyancy and special design features of the SkyCat offer a virtually zero catastrophic failure mode. With the internal hull pressure maintained at only 1%-2% above surrounding air pressure, the vehicle is highly tolerant to physical damage or to attack by small arms fire or missiles.
Storm and turbulence: while on long-haul flights weather patterns would be flown to avoid bad weather, the sheer mass of the hull largely dampens out the effect of turbulence just as a large tanker rides through rough seas.
Lightning strike: constructed mainly from composite materials, the SkyCat offers a poor lightning target and, should it be struck, built-in protection devices ensure that the risk to the vehicle and its cargo is minimal.
Structural vulnerability tests: a series of tests were carried out by the UK Defence Evaluation and Research Agency (DERA) on a Skyship 600, an earlier airship built by the Munk team to a similar pressure-stabilised design. The picture below shows the airship two hours after several hundred high-velocity bullets were fired through the hull. Even after this intensive assault, the vehicle would have been able to return to base.
