CMOS Checksum error. What is it a checksum of? The entire content of the CMOS data? Some specific parameter data? What type of checksum is it? Is it CRC-8?... something else? I understand that this error indicated a checksum mismatch. But what is the second checksum that the CMOS checksum is being compared to? Why do these two checksums need to match?
All our blimps are filled with the inert gas helium. Helium gas is non flamable, non combustible and non toxic. Since it is a compressed gas, the only danger comes from improper handling of the cylinders when moving them or improperly using the pressure regulator. If a hole does develop the blimp will not dramatically fall and cause injury.
Lockheed wins order for blimps as oil industry looks to save money. Straightline Aviation signed a letter of intent to purchase up to 12 Lockheed Martin Hybrid Airships. Lockheed Martin won an order for as many as 12 airships worth $480 million as lower crude prices spur cost-conscious oil and gas companies to turn to blimps to carry workers and cargo to remote locations.
