Re: Going back in time to the pre-jet era

I read that some operators of Douglas DC-6 and DC-7 types would have been wiser and further ahead to stick with DC-6 only to avoid engine issues with the more powerful engine of the DC-7.

Going back in time to the pre-jet era

If you could go back in time with the ability to consult the CEOs of the various airlines in the twenties through the fifties who would you have the most to say to about their choices for aircraft and their ultimate successes as airlines. Assume you as a time traveler know how all the prop planes wo...

Re: Latest count of 747 Combis still flying

Here is a hypothetical. Say KLM decided to stay with Combis as long as possible given engineering limits? Assuming the business plan analysis is firmly Combi would KLM be better to pay Boeing to certify a 747-8 Combi rather than spend the ongoing check and maintenance rebuild costs to keep 744 Combi...

Is the conversion of Boeing 744s to Freighter over now?

Are the economics such that enough used 744 freighters and converted 744 freighters are available and the cost of conversion no longer supportable by any business plan?

Ok right you are. I now have read those two 747-8s that were declined by bankrupt Transaero were bought by the USAF in 2017 for retrofitting to become the two replacement Air Force Ones.

Looking at the 747-8s stored in November, 2015 by Boeing there were two aircraft built for but not taken up by Transaero Airlines due to bankruptcy. They are MSN424416 (LN1519) and MSN424417 (LN1523). The aircraft types are both labelled as 747-85M. Were these built with Combi specs but to be config...

As already mentioned, Canadian Pacific operated the DC-6B to YCG for some years on their milk-run route between YVR and YYC. Until flights to AMS began including stops in YYC, that was CP's only flight to YYC for quite a few years. The DC-6B replaced the Convair 240 if memory correct. I flew on tha...

On the topic of Boeing 747 converted freighters: did Boeing do their own conversions way back when to make the 747-100SF, the 747-200SF and the 747-200BSUDSF? Was IAI/Bedek or another aftermarketer doing those as well?

Re: Was the nose loader door ever just an option for 747 F?

BCFs are heavier than production freighters with less cargo payload available and lower floor loading limits on the main deck. All 747-400 all pax aircraft converted to freighter have a highter operational empty weight ( OEW) than factory built 744F's, because of the increased strength construction...

Re: Was the nose loader door ever just an option for 747 F?

I think the big number of conversions to 747 freighters by Boeing and IAI/Bedek speaks volumes about the utility and desirability of side cargo door only without nose loader.

Re: Was the nose loader door ever just an option for 747 F?

No, but the Side Cargo Door was an option on the very first 747 freighters. There were a few, very few without it. The first LH frame (the prototype, D-ABYE), and at least one for JAL (JA8132) come to my mind. The first 747-200F and a few 747-200C's were delivered with only the nose cargo door. Del...

Did any iteration of the factory 747 freighter ever get delivered with just side cargo door. I read the threads that state the 747-8 Fs all come standard with front and side loading doors. Did Boeing always make the nose loader standard in spite of weight uptick?

Re: Ultimate fate of Air Canada's three Combi 744s

As I understood it the weight increase resulted from a sturdier and fixed separation between PAX and cargo compartments. The landing gear was necessary for the heavier weighted aircraft. I wouldn't think a Pax 747 would need heavier landing gear. The result was a bit of a failed experiment as the pl...

Re: Ultimate fate of Air Canada's three Combi 744s

Would the Bedek conversions have changed the weight problem the Combis had due to heavier landing gear and heavy fixed bulkhead between the main deck cargo and passengers?

The third Combi was used by Air India for a few years in a fr...

Re: Latest count of 747 Combis still flying

On the other hand if the two Air Canada Combi 744 had fixed bulkheads wouldn't they weigh a large amount heavier even after full freighter conversion? Surely their conversions would not have included a complex bulkhead removal?

Re: Latest count of 747 Combis still flying

I have heard the 3 Air Canada 744 Combis were built with heavier fixed partitions that made the aircraft heavier and less flexible than would have been optimal for varying layout. Full freighter conversion probably made that issue moot?

Prior to the Pacific Western Air 737s into Castlegar how large were the predecessor airliners into that difficult airport? I cannot find too much that goes back to the sixties and early seventies. I knew that the early days were hell for the airlines with cancellations due to the weather.

I have read all the older threads about 747-400 Combi counts and some 744 Combis being converted to PAX. With the virtual zero probability of 748 Combis ever being produced I wonder what the number of 744 Combis still operating is now. What is the oldest flying 744 Combi and what is youngest? Thanks...
