  • 00:03

    The 757 entered service in 1983, and more than  1,000 were delivered over the next 20 years.  

  • 00:11

    It has been a great success for Boeing and popular  with many airlines, in particular with its long  

  • 00:17

    range and versatile operation in hot, dry,  and high locations. Production ended in 2004,  

  • 00:25

    and it is now disappearing from airline  fleets, with no real replacement options.

  • 00:32

    By the 1970s, Boeing had started to see strong  success with its jets. The Boeing 707 is widely  

  • 00:39

    credited as the first successful aircraft  of the jet age (the Comet was the first,  

  • 00:45

    but several problems held it back). And the  Boeing 727 had done very well for Boeing,  

  • 00:51

    opening up new options for jets on shorter  routes and at smaller airports. Until the  

  • 00:57

    1990s, it was the most produced jet  aircraft (until the 737 took over). 

  • 01:04

    Boeing, and operating airlines, wanted a successor  to the popular 727. There was a desire for greater  

  • 01:11

    capacity, and one of the first proposals  was to stretch the 727. But airlines were  

  • 01:18

    also interested in efficiency, with a preference  for two engines instead of the three-engine 727.  

  • 01:24

    This would lower operating costs, and ultimately  led to the new clean-sheet design of the 757.

  • 01:32

    Although it was a replacement for the 727, much  of its design and inspiration came from the larger  

  • 01:38

    767. Development of the 767 had started earlier,  so the 757 ended up ‘borrowing’ from its design.  

  • 01:48

    This saved time and cost and is not  uncommon in aircraft development.  

  • 01:53

    Similarities included the two-person  cockpit and much of the interior fittings. 

  • 02:00

    Five aircraft were involved  in a seven-month test program.  

  • 02:04

    This proceeded with surprisingly few delays  and led to an increase in the range quoted.  

  • 02:09

    It received its FAA certification in December  1982 and UK CAA certification in January 1983.  

  • 02:19

    The first aircraft entered service with  Eastern Airlines on January 1st, 1983.

  • 02:26

    The 757-200F cargo variant followed soon and  entered service in 1987 with UPS. Overall,  

  • 02:35

    80 freighters were ordered, with FedEx Express,  UPS Airlines, and SF Airlines in China the main  

  • 02:43

    operators. There is also a 757-200 Combi freight  version for combined passenger and cargo use.  

  • 02:51

    Nepal Airlines was the only  new customer for this in 1986. 

  • 02:58

    In 2001, Boeing launched a passenger to freight  conversion version – with passenger facilities  

  • 03:04

    removed, cargo door added, and the fuselage  floor strengthened. The first aircraft to be  

  • 03:11

    converted were retiring 757-200s from British  Airways. This conversion has been popular  

  • 03:18

    since – according to data from ch-aviation.com,  there have been 128 conversions to date.

  • 03:26

    The 757-300 stretched the fuselage by  just over seven meters. Capacity was  

  • 03:33

    increased to a maximum of 295 (from an  exit maximum of 239 for the 757-200).  

  • 03:41

    Typical capacity though was 243, up from 200. The 757-300, though, was not a great success,  

  • 03:51

    with only 55 aircraft built. The increased size  led to a reduction in range, and it ended up  

  • 03:58

    as a fairly niche offering. The widebody 767  offered a greater capacity than the 757-200,  

  • 04:06

    without compromising on range. But the 757 could  access smaller airports. It also came late in the  

  • 04:14

    development of the 757 (the 757-200 had been in  service for 16 years when the -300 launched).

  • 04:23

    The 757 is known for its range and its performance  in hot and dry and high-altitude environments.  

  • 04:30

    This makes it a very capable and versatile  aircraft that has suited many airlines well. 

  • 04:37

    The 757-200 offers a range of  3,915 NM (7,250 kilometers).  

  • 04:46

    This is much higher than other narrowbodies.  For comparison, the 737-800 has a range of 2,930  

  • 04:55

    NM (5,765 kilometers) – and also a lower  typical passenger capacity of 162 versus 200.  

  • 05:06

    The newer and larger 737 MAX 10 still  falls short of the 757 on range. 

  • 05:14

    With this range, the 757 can easily handle  US coast-to-coast flights as well as offering  

  • 05:20

    transatlantic narrowbody routes. Icelandair  has even operated it on a few one-off flights  

  • 05:26

    from Reykjavik (KEF) to San Francisco (SFO)  – a distance of 3,653 NM (6,765 kilometers). 

  • 05:39

    In more regular service, Delta Air Lines has  operated the 757-200 between Atlanta and Brasilia,  

  • 05:46

    Brazil – a route of 3,542 NM (6,560 kilometers). Its performance has also set it apart from other  

  • 05:58

    narrowbodies. Importantly, it has a higher  thrust-to-weight ratio. It can operate from  

  • 06:04

    shorter runways, with a lower take-off speed, and  has higher performance in thin air environments. 

  • 06:11

    With this performance, US airlines have been  able to schedule it widely, including hot,  

  • 06:17

    dry, or high altitude airports such as Denver and  Bogota. It can also serve smaller runway airports,  

  • 06:25

    giving it a big advantage over widebodies such  as the 767 (and even the 737 at some locations). 

  • 06:33

    One interesting side-effect of its design is  that it produces powerful wingtip vortices  

  • 06:39

    (more in some cases than 767 or 747).  

  • 06:43

    This has reduced somewhat with winglets, but  the 757 is classified as ‘heavy’ by air traffic  

  • 06:49

    controllers to acknowledge the impact of  this and the aircraft spacing required.

  • 06:55

    The 757 has been especially popular with US  airlines, with all of the major legacy airlines  

  • 07:02

    (American Airlines, United Airlines, and  Delta Air Lines) operating it. American  

  • 07:08

    Airlines operated the largest fleet of  142 (including many acquired from TWA).  

  • 07:15

    It retired them in 2020 amidst  pandemic-related fleet simplification. 

  • 07:21

    Following American’s retirement, Delta Air Lines  became (and remains) the largest 757 operator.  

  • 07:28

    As of June 2021, it still operates 127  aircraft. United Airlines still operates 72. 

  • 07:39

    The 757 remains a popular freighter option, which  is likely to outlast passenger use. FedEx Express  

  • 07:46

    operates 109 aircraft, UPS Airlines operates 75,  DHL Air operates 23, and Chinese SF Airlines 36.

  • 07:59

    The 757-200 has also seen plenty  of specialized uses. It has been  

  • 08:04

    a popular choice for government use, used for  presidential transport by Mexico, Argentina,  

  • 08:11

    Brunei, Saudi Arabia, Kazakhstan, and the US. While the US Air Force modified 747s that serve as  

  • 08:19

    Air Force One are more famous, the government  fleet also includes 757s (with designator C-32).  

  • 08:27

    These serve as ‘Air Force Two’ when  carrying the Vice President – but also  

  • 08:32

    are used by the President. The aging 757s  (between 22 and 30 years old) were due to  

  • 08:40

    be replaced, but this has been halted. NASA previously used a 757 for its ARIES  

  • 08:47

    (Airborne Research Integrated Experiments System)  program for safety and operations research. And  

  • 08:54

    the New Zealand Air Force operates two converted  Combi aircraft for transport and VIP use.

  • 09:02

    The 757 boomed in the early 1990s, with more than  100 aircraft being delivered each year at peak.  

  • 09:10

    This had slowed by the early 200s. And the events  of 9/11 and the slowdown in aviation followed  

  • 09:17

    significantly reduced demand for the 757 (with  smaller widebodies becoming more popular).  

  • 09:24

    Orders being swapped to the 737 (most notably from  Continental Airlines in 2003) sealed its fate.  

  • 09:33

    Production of the 757 ended in 2004, and  Boeing delivered the final aircraft in November  

  • 09:40

    2005 to Shanghai Airlines – the 1,050th 757 built. 

  • 09:48

    The 757 has suffered several earlier than  planned retirements during the pandemic. As  

  • 09:54

    already discussed, this saw the early retirement  of American Airlines’ fleet, amongst others. 

  • 10:00

    As of June 2021, 508 aircraft remain in use with  46 carriers. With aircraft aging, there could  

  • 10:09

    well be more retirements before we are fully  out of the pandemic, but we are likely to see  

  • 10:14

    the 757 in service for some time. Delta has not  confirmed further retirement plans as yet. United  

  • 10:23

    Airlines is more likely to retire aircraft with  orders for A321XLR aircraft set to replace them.

  • 10:31

    Boeing ended production of the 757  without developing a direct replacement.  

  • 10:37

    The 737 MAX offers neither the range nor the  hot and short-field performance of the 757  

  • 10:43

    (although it does improve efficiency).  Many view this as quite a loss for Boeing. 

  • 10:49

    The upcoming A321XLR is being seen by some  airlines as a good replacement option.  

  • 10:56

    It will offer an impressive range of up to 4,700  NM (8,700 kilometers), taking narrowbody flying  

  • 11:05

    further than ever before. But it won’t match the  757s performance in hot and high environments. 

  • 11:13

    American Airlines was one of the  first airlines to opt for the A321XLR,  

  • 11:18

    and it has 50 aircraft on order – likely  to take up many of the old 757 routes.  

  • 11:25

    United is doing similar, also  with 50 aircraft on order. 

  • 11:30

    As for Boeing, there’s still no confirmed  replacement. There has been discussion of  

  • 11:35

    a 757X that would re-engine the 757 and offer  similar specifications, but no plans from Boeing.  

  • 11:43

    It was denied as a possibility in 2020,  largely due to the 757s high production cost.

  • 11:52

    The Boeing New Midsize Aircraft (NMA),  also dubbed the 797, was originally seen  

  • 11:59

    as a replacement for the 757 (but most likely as a  widebody). The idea had seen interest from United  

  • 12:07

    (a major Boeing customer) and Delta  Air Lines, Qantas, and Icelandair. 

  • 12:13

    NMA plans were dropped in 2020 though, with  attention and funds diverted by ongoing 737 MAX  

  • 12:20

    issues, as well as the pandemic. The  launch of the A321XLR also led to a  

  • 12:26

    re-think of what should be offered. There are plenty of options for  

  • 12:30

    where Boeing could go next. Re-visiting  757X ideas, a similar re-engined 767X,  

  • 12:38

    a return to 787-3 plans, or a new clean-sheet  narrowbody are all possible. No doubt it will  

  • 12:46

    launch something soon or risk Airbus taking over  more of the market. Whether this will offer the  

  • 12:52

    same features as the 757 remains to be seen. The 757 remains a great aircraft but clearly  

  • 13:01

    falling out of favor as other  options improve. Feel free to  

  • 13:06

    discuss its highlights and your thoughts  on any future replacement in the comments.
