Here is an page from flight international that probably should be posted under c/n 2501 but since there isn't much here and has some interesting speccs for the H-500/U-5 and it has a picture of N10036 c/n 6 I decided to post it here.

link to c/n 2501, N5444E

While trying to figure out the Ferry Route, I was hoping to come up with some more Twin photos here at Air History or where I found a bit more about the ferry flt from Norwood MA at the Malta site.

or here

The Malta site shows Edward A. Cunningham as pilot on Twin Helio #6 as well as twin Helio Twin Helio #1 and 2 #6 was the 5th Helio Twin to refuel at Malta on 03/'66.

The Malta site also shows a ferry route from Boston, Torbay, Santa Maria, Valencia to/Beirut which seemed like kind of a confusing route to take to get to Malta. The ferry permit shows final destination as Thailand another 4000 miles, even the final destination of Charbatia an Air Base in Eastern India is 2700 miles but it got sorted out with BW's help.

The Atlantic crossing route on all of the 5 twin helios, is Torbay to Santa Maria the shorter southern route, with 2500 mile range, turbocharged twin engines and equipped with oxygen to flyover most weather it seems to be the logical route.

sorted route; using BW's info
Boston-(actually Norwood MA)
Torbay, (Newfoundland near St Johns)
Santa Maria, (island in the Azores, close to San Miguel) ‚Äč
Valencia, (Spain)
Luqa, (Malta)
Beirut, (Lebanon)
should be a stop between Beirut and Thailand
Thailand, maybe Udorn
Charbatia Air Base, India

see BW's post below

Torbay is Newfoundland near St Johns.  Santa Maria is island in the Azores up close to San MIguel (which is now the major airport) Valencia, Malta, Bierut all are fine.  Seems like there must have been another stop somewhere between Beirut and India. For Thailand in those days the big Helio/CIA/ Etc operational base was Udorn (Udorn Thani) which is in the north of Thailand about 30 miles (maybe) from Vientiene, Laos.  Back to North India not too far back across Burma and Bangladesh.  I have been to most of those SE Asia (and India - Bangladesh)places for one reason or another.

They departed from Norwood, Mass. (rather than Canton one mile away)  because that was where the fuel, paved runways and the paperwork were located.
Cheers BW
