My present employment has us slinging diesel fuel on a very regular basis, using drums in nets which are a PITA since you have to sling the empties back as well as the nets. I know there are some fuel bladders, designed to be heliportable, available; we could sling them out full, and take a load of collapsed, folded empties back in the cabin. A google search only came up with two manufacturers, ATL in New Jersey and FTP in the UK. Any other sources anyone knows of? The sizes we'd be working with would be 200 - 700 gallons.
Thanks in advance.
