Seems to me like redundancy and failure analysis was an afterthought for the design team. This is a case that proves, do a complete analysis before actually going ahead with a build. I have worked at many places where they wanted me to just design on the fly. I would fight them to let me do a complete requirements, failure, and design analysis before doing the full project. But, I was told otherwise.
For the record, that company was audited. After which, complete analysis was a requirement.
Reports suggest that the pilot believed the faulty airspeed readings and was pitching the aircraft up until it stalled. The aircraft was capable of flight, it just had a bad instrument. If I'm ever faced with a similar situation I hope I don't make the same mistake.
There was a crash in Washington DC back in the Eighties that was similar. The engine thrust sensors in the aircraft had iced up during takeoff and were giving an erroneous reading. Even though the aircraft was stalling the pilot never increased power because he believed that one instrument rather than the data he was collecting from all the other sources.
A postcard or post card is a rectangular piece of thick paper or thin cardboard intended for writing and mailing without an envelope. There are novelty exceptions, such as wood postcards, made of thin wood, and copper postcards sold in the Copper Country of the U.S. state of Michigan, and coconut "postcards" from tropical islands.
In some places, it is possible to send them for a lower fee than for a letter. Stamp collectors distinguish between postcards (which require a stamp) and postal cards (which have the postage pre-printed on them). While a postcard is usually printed by a private company, individual or organization, a postal card is issued by the relevant postal authority.
