“USS Akron (ZRS-4) was a helium-filled rigid airship of the U.S. Navy which operated between September 1931 and April 1933. She was the world’s first purpose-built flying aircraft carrier, carrying F9C Sparrowhawk fighter planes which could be launched and recovered while she was in flight. With an overall length of 785 ft (239 m), the Akron and her sister ship the Macon were among the largest flying objects ever built. Although the LZ129 Hindenburg and the LZ130 Graf Zeppelin II were some 18 ft (5.5 m) longer and slightly more voluminous, the two German airships were filled with hydrogen, so the US Navy craft still holds the world record for helium-filled airships.
The Akron was destroyed in a thunderstorm off the coast of New Jersey on the morning of 4 April 1933, killing 73 of the 76 crewmen and passengers. This accident involved the greatest loss of life in an airship crash.”
I have had this scanner for almost 4 years and scanned everything from brochures, photos, receipts and multiple sizes of papers. It scans at 30 pages per minute and can do the front and back at the same time. The scanning speed is very fast but it is quiet too. It is easy to clean the scanning mechanism after scanning a dusty scrapbook or old photo. Making the next scan as good as the first!
If you are looking for an all in one negative/slide/photo scanner look no further. This thing is great. There is a brief learning curve and you need to experiment with all the settings and how to use the included holders. Also, when working with negatives and slides dust is not your friend. Compressed air and a soft brush are helpful. We have been using the Espon V550 everyday for over a year and have had zero issues.
