The licence they piggyback on does have Part121 and Part135. I however don't want to mention names.
It is always nice to hear both sides of the story and then the truth. How about it Sabian Air? Give us your side of these allegations.
I also heard from the engineer that worked on a certain Seneca mentioned (with fuel problems) that the fuel cross-feed had its plumbing back to front, so when the pilot tried to cross-feed, it tried to do this from the empty tank. This seems to have been omitted in the original story. In this case, you certainly can't blame the pilot.
