Hi,
I don't know if it was possible at all, but certainly neither practiacal nor was it permitted in real life commercial service. FL250 is about all you can expect.
Best regards, Volker

While you might be able to get the old girl that high when she is very light you would not not have a lot of power left even with the R-3350s with their complex plumbing for boosting the air supply to the engines. Secondly the cabin superchargers would run out of "power" to keep the cabin altitude low enough for mere humans. If the structure of the airplane could support a survivable cabin differential. All of this was still quite new at the time of the first Connies.
More likely is that this was simply a slight exaggeration or typo in the old article.
Cheers Stefan

Hi,
a typo with a 3 instead of a 2 is not unlikely, indeed.

were the C-69s ever deployed in combat, or did they just stay in the mainland?

Just catching up on a few things so forgive me if already mentioned in the seven pages... looling great...but didn't the 049 have smaller fins and rudders?

Hi,
the L-49 saw little service as a C-69 transport, it was only introduced in military service in early 1945 and it was still quite imature by then. Actually, at some time, C-69's were banned from flying outside the continental USA because of their low reliability. However, one ditched off a french airfield when misjudging the reflection of the approach lights in the sea.
The L-49 to L-749A series shared the same fins and rudders, they were later extended for the L-1049 series. The WV-1 Airborne Early Warning planes based on the L-749 were later fitted with these extended outboard fins and rudders for better lateral stability and the one sourvivor still has them. The effect of the center rudder wasn't that good aft of the large dorsal radome and most late AEW Super Connies had them fixed in position.
Best regards, Volker

So too was the Avro Shackleton MR.3 as used by the SAAF. This option was seldom used because in practice the boats could not be launched successfully (i.e. they refused to stay in in one piece...). One such boat, complete with survival gear, can still be viewed at the SAAF Museum in the Ysterplaat Air Force Base, just outside Cape Town. Of interest is that the manufacturer of the little inboard engine fitted to these boats was Vincent, better known for their up-market 1000cc v-twin motorcycles. The speedpacks remind me of the SB-17s that were modified to carry boats for sea rescue operations.

OBTW, besides the boat-thing, here's another similarity between the Shack and the Connie: The Shack didn't have a triple-tail... but it did have a double-tail. So too was the Avro Shackleton MR.3 as used by the SAAF. This option was seldom used because in practice the boats could not be launched successfully (i.e. they refused to stay in in one piece...).

All propliners were limited to FL250 due to the lack of a passenger oxygen system. A very light 049 might have reached FL350, but it would have had to be very light indeed and then what would be the point?
