I agree with Herman: A nice smoking Eight is greeting visitors here at HJG.
Nicely done.

That's Jim's new 1959 liveried "coal burning" (steam powered) DELTA AIR LINES DC10-11  .... released as part of this latest/yesterdays HJG website update  I've worked up a number of other images similar this one .... which I might post later on as part of another presentation  Mark C AKL/NZ |

How many tons of coal..err..kerosine are 'wasted' while 'marking' the runway with the 'A DC-8 was here!'-mark? Now you have made me curious about your coming presentation. I'm sure that it will be as great as the other presentations here in the forum! Klaus |

The early P&W JT3 SERIES turbojet engines on B707-120/-138 and DC8-11/-12 aircraft consumed "a lot of fuel" even in the best of operating conditions .... and especially during T/O in particular .... BUT .... it was the Water/Methanol solution which was used to augment engine thrust (for around 3 minutes only .... it increased the density of air passing though the engines and which subsequently boosted engine thrust by around 12%) that was responsible for all the thick black plumes of smoke and soot .... and the associated "NOISE" was, apparently, something else to be believed/experienced too Within about 4 years .... from 1958 to around 1961 (or there-abouts) .... these early P&W JT3 SERIES turbojet engines on civil aircraft were replaced with "cleaner burning" .... but .... almost as "NOISEY" and simularly thirsty P&W JT4-A SERIES turbojet engines which were fitted to B707-220/-320 and B720-A along with DC8-20/-30 aircraft .... along even the more powerful P&W JT3-D SERIES fanjet engine option too which were fitted to B707-120B/-138B/-320B and C along with B720-B as well as DC8-50/-61/-62/and -63 aircraft from the early 1960's also. The 1950's era represented possibly "the greatest period of change" within civil aviation industry .... with aircraft/airlines transitioning from propliners to jetliners .... quickly followed by an equally great transition from turbojet to fanjet engine power during the early 1960's .... and which was also then followed by another great transition from narrow-body to wide-body jetliners and "big turbofan power" during the early 1970's with the advent of the A300B, B747, DC10, and L1011 aircraft .... and all of which occurred within the time frame of less than a couple of decades. It was "QUITE A FASCINATING PERIOD" It's this "great transitional period" that "I hope" to be able to present an illustrated feature regarding .... sometime within the next several weeks .... subjevt to other work here as well as real world influences too.

Whenever I or somebody else has a question about aviation-history, I/he/she can be sure that Mark C. replies with interesting information/knowledge.
Thanks Mark for 'enlighten' me/everybody else about the differences between pure turbojets and their more efficient 'cousins' the fanjets.
