Doc, all kinds of people -- in all kinds of planes -- fly over blue water. It's just, it is not considered safe enough for American commercial airline services (mainly to protect the passengers). A good example is corporate pilots. The Gulfstream does not have ETOPS certification (AFAIK) but since it is a private plane, you can fly it anywhere you please. You just can't operate an airline and sell tickets on such a flight. This isn't especially "dangerous," it just doesn't meet the super safety rules we have for commercial carriers.
Delivery flights by Boeing and Airbus also go over blue water. So the empty A320s and 737s can be seen doing pretty exotic overwater flights, even if they do not have ETOPS.
You are confusing aircraft certification requirements with aircraft operational requirements. Part 25 are the certification requirements for the 717. The operational requirements for its commercial operations are Part 121, and for non-commercial operations (ferry in this case) is Part 91.
The plane is designed to Part 25, and that never changes. The aircraft can operate Part 91 and Part 121 the same day.
Here are some photos. Rather than fuel bladders, I would call them fuel tanks. The question I would have is how are these tanks entered into the fuselage? They seem too big to come thru the main entry door or emergency exit. Are they loaded partially assembled, and assembled inside the fuslage?

They are designed to fit through the passenger door. You just have to remember that the interior is removed in the area, including seats, bulkheads, front galley if it is in the way.
If you look closely even the overhead bins are missing, which I am not sure if they are removed for weight issues or clearance.

Quoting DescendVia (Reply 5): It's not scheduled either, so you might be able to fly under part 91, not completely sure about that though.
All airline deliveries I have been involved the past 4 years were planned and executed as part91 flights, including the use of the plane registration as the flight call-sign. This was the case from new aircraft departing from Seattle and used ones departing from places like Singapore, Stansted and Taipei.
BTW, bizjets have no ETOPS certification, but planning over-water take ETPs into consideration.

I have seen these tanks in person and they are around 30 inches wide and around 60 inches long. The 717 L1 door clearance is 34.7 inches and the floor is about 120 inches across. More than enough room to fit through the L1 door.

You can go even smaller than that. My wife's uncle bought a King Air C-90 at Beech and it was flown from Wichita to Johannesburg. Okay, they didn't fly straight across the ocean but it did involve some extensive water hops.

Quoting Sasha (Reply 13): Thinking of it - they do manage to somehow get Twotters, Q400s from North America to Europe and vice versa - Dornier 328 and ATRs
Canadian operator Kenn Borek Air (based in YYC) ferries several Twin Otters every year between the Canadian Arctic region where they often operate on skis at temperatures of -40 or -50C all the way to the Maldives, where the aircraft and crews operate on floats for Maldivian Air Taxi. Assuming they start at their home base in YYC, with all the fuel stops needed that's a trip of roughly 10,000 nm.
Kenn Borek DHC-6s have frequently landed at both the North and South Poles. Second photo below shows two of them at the South Pole.Their fleet includes almost 40 Twin Otters.
