Here's a comparison of the major differences between the 737-100 and 737-200:

The 737-200 had a number of improvements over the 737-100, including a more powerful engine and a larger cargo capacity.

The 737-100 was the smallest variant of the 737 aircraft family, launched in February 1965.

It entered service with Lufthansa in February 1968 and had a unit cost of US$3,600,000, equivalent to $32,600,000 in 2024.

Only 30 737-100s were produced, with 22 going to Lufthansa, five to Malaysia–Singapore Airlines, and two to Avianca.

The 737-100 was largely overshadowed by its bigger 737-200 sibling, which entered service two months later.

The original engine nacelles incorporated thrust reversers taken from the 727 outboard nacelles, but they proved to be relatively ineffective.

A 48-inch tailpipe extension and new target-style thrust reversers were introduced in 1968 to improve the thrust reversal system.

Longer nacelle/wing fairings and improved airflow over the flaps and slats were also introduced to give the aircraft a boost to payload and range.

The production line introduced an improvement to the flap system, allowing increased use during takeoff and landing.

The first 737-100, later used by NASA, was retired after 30 years in 2003, and the last 737-100 built was broken up in 2006.

The last surviving example of the 737-100 is the first aircraft used by Boeing as a prototype, now on static display in the Museum of Flight in Seattle.

The -200 series is a key part of the Boeing 737 family, and it's worth taking a closer look at its unique features. The 737-200 has a length of 100 ft 2 in (30.53 m), which is about 1.5 m longer than the 737-100.

One of the main differences between the 737-100 and the 737-200 is the length of the fuselage. The 200 is about 1.5 m longer than the 100 series. This extra length allows for a greater passenger capacity, with the 737-200 seating 130 passengers compared to the 737-100's 118.

The 737-200 has a cargo capacity of 875 cu ft (24.8 m), which is significantly more than the 737-100's 650 cu ft (18 m). This makes it a popular choice for airlines that need to transport large amounts of cargo.

Here's a comparison of the 737-100 and 737-200:

The 737-200 Advanced is a variant of the 737-200, and it has a few key differences. The main changes are longer nacelle/wing fairings, an improved flap system, more powerful engines, and a greater fuel capacity.

The 737-700C is a version of the 737-700 with a large cargo door on the left side. This is what differentiates it from other 737-700s.

Most 700Cs have been delivered as C-40A Clipper of the US Navy. This is a significant application of the 737-700C variant.

The 737-700C still has many cabin windows, unlike some of the other variants that have been converted for cargo use.

The Boeing 737 family has seen its fair share of order fluctuations. As of September 2025, 17,040 units had been ordered.

The 737 had the highest cumulative orders for any airliner until it was surpassed by the A320 family in October 2019.

A significant drop in orders occurred in 2019, with 737 orders plummeting by 90%. This was largely due to the 737 MAX orders drying up after the March grounding.

The 737 MAX backlog fell by 182, mainly due to the Jet Airways bankruptcy, a rare occurrence in the industry.

Boeing's airliner backlog experienced a drop for the first time in at least 30 years.

The Boeing 737 has undergone significant transformations over the years, resulting in four distinct generations of aircraft.

The 737 Original, also known as the 737 Jurassic, was the first generation of the Boeing 737 family, consisting of the -100 and -200 series.

The 737 Classic, which included the 737-300, 400, and 500 series, was the second generation of the Boeing 737 family, produced from 1984 to 2000.

A total of 1,988 Classic series were delivered during this period.

The 737 Classic was eventually replaced by more efficient aircraft, such as the 737 Next Generation and the A320 family, due to rising fuel costs in 2008.

The 737 Next Generation, which included the 737 MAX, was the fourth generation of the Boeing 737 family, designed to compete with the Airbus A320neo family.

The 737 MAX was launched in 2011 and had its first flight on January 29, 2016, with the first delivery being a MAX 8 on May 6, 2017.

The Boeing 737 Next Generation, also known as the 737NG, was introduced in 1997 and has been a game-changer in the aviation industry. It's been produced since 1996 and has a total order of 7,097 aircraft.

The 737NG was designed to re-engine the 737 with the high bypass ratio CFM56-7, which greatly improved fuel efficiency. This was a crucial move by Boeing to stay competitive in the single aisle market.

One of the key features of the 737NG is its redesigned wing, which has a wider wingspan and larger area, allowing for greater fuel capacity and longer range. This has enabled the aircraft to carry more passengers and fly farther than its predecessors.

The 737NG is available in four main models: the -600, -700, -800, and -900, which can accommodate seating for 108 to 215 passengers. This flexibility has made the 737NG a popular choice among airlines.

Here's a list of some of the countries that have operated the 737-700 variant:

The original 737s, also known as the 737 Jurassic, were the first generation of the Boeing 737 family.

They were part of the -100 and -200 series, which marked the beginning of the iconic 737 line.

These aircraft were the first to bear the 737 name, and they paved the way for the many generations that followed.

The 737 Original was a significant milestone in aviation history, and its impact can still be felt today.

It's amazing to think about how far the 737 has come since its humble beginnings as the 737 Original.

The Boeing 737 Classic is a significant chapter in the history of commercial aviation. Produced from 1984 to 2000, a total of 1,988 Classic series were delivered.

The Classic series was a popular choice among airlines, but as fuel prices rose, carriers began to retire these aircraft in favor of more efficient models. In 2008, United Airlines announced it would retire all 94 of its Classic 737 aircraft, replacing them with A320 family jets.

The Classic series was eventually phased out as airlines sought to reduce fuel consumption. This led to increased competition between Boeing and Airbus, which has since become a duopoly competition.

Here are some key facts about the Classic series:

The fourth generation of the Boeing 737 family is a significant upgrade, offering improved efficiency and range. It's powered by the CFM LEAP-1B engine with a very high bypass ratio.

The 737 MAX is offered in four main variants, typically seating 138 to 230 passengers and flying up to 3,825 nautical miles. This generation replaces the 737-700, -800, and -900 models.

Boeing announced plans for the 737 MAX in July 2011, with American Airlines intending to order 100 of these aircraft. The MAX had its first flight on January 29, 2016, and gained FAA certification on March 8, 2017.

As of January 2019, the 737 MAX series had received 5,011 firm orders. This was before the series faced significant setbacks due to two hull loss crashes that caused 346 deaths.

The 737 MAX was grounded by civil aviation authorities in March 2019, and production was suspended in January 2020. However, the FAA cleared the MAX to return to service on November 18, 2020, after a series of recertification test flights.

The oldest active Boeing 737s are a testament to the aircraft's durability and longevity. One of the oldest is the Peruvian Air Force FAP 354, with a manufacturing serial number (MSN) of 20221.

MSN 20221 has been in service for a long time, and it's not alone. The Indian Air Force also has some old B737s, with MSNs 20483 and 20484, both of which are still flying.

These aircraft have been well-maintained and have been used for a variety of purposes. Let's take a look at some of the oldest active B737s:

These aircraft are still going strong, with some of them even used for flight operations.

The Boeing 737 has undergone significant design developments over the years, resulting in four generations of the aircraft family.

The first generation, also known as the "Original" series, was launched in February 1965 and included the 737-100 and -200 models, as well as military variants like the T-43 and CT-43.

These early models were followed by the second generation, or "Classic" series, which was introduced in 1979 and featured the 737-300, -400, and -500 models.

The 737 has continued to evolve, with each new generation building on the same basic design.

Here are the four generations of the Boeing 737 family:

The Boeing 737 has undergone significant design developments since its initial concept in 1964. The first generation "Original" series featured a unique engine design with podded engines on the aft fuselage, which were later relocated to the wings to improve structure and simplify seating.

The 737's fuselage was derived from the 707, allowing for six-abreast seating compared to its competitors' five-abreast seating. This design choice gave the 737 a significant advantage in terms of passenger capacity.

The wing airfoil sections were based on those of the 707 and 727, but were made thicker to achieve a substantial drag reduction at high Mach numbers. This design modification improved the aircraft's performance and efficiency.

The 737 has evolved into four generations, with each generation featuring significant design improvements and new variants. Here's a breakdown of the different generations:

The 737's engine design has also undergone significant changes over the years, with the introduction of more efficient and quieter engines.

The cockpit of the Boeing 737 is a fascinating area that has undergone significant changes over the years. The original 737 cockpit used a hydro-mechanical flight control system, which is similar to the Boeing 707.

This system relies on steel cables to transmit pilot commands to hydraulic boosters attached to the control surfaces. The primary flight controls have mechanical backups, which ensure safe flight even in the event of a total hydraulic system failure or double engine failure.

In the event of such a failure, the servo tabs take over, controlling the elevators and ailerons through cables connected to the control yoke. The pilot's muscle forces alone control the tabs in this mode, known as manual reversion.

The 737 Next Generation series introduced a modern glass cockpit with six LCD screens, designed to retain crew commonality with previous 737 generations. This means that pilots familiar with older 737 models can easily adapt to the new cockpit.

The 737 MAX, on the other hand, features a 4-screen LCD cockpit with a landscape orientation, manufactured by Rockwell Collins. This design is derived from the Boeing 787 Dreamliner and retains many similarities with previous 737 cockpits to maintain commonality.

Here's a brief overview of the different cockpit generations:

Wingtips play a crucial role in improving fuel efficiency and reducing drag on the Boeing 737 aircraft.

The original 737 series didn't have wingtip devices, but they were later introduced to enhance fuel efficiency.

The 737 has evolved four winglet types: the 737-200 Mini-winglet, 737 Classic/NG Blended Winglet, 737 Split Scimitar Winglet, and 737 MAX Advanced Technology Winglet.

The 737-200 Mini-winglets are part of the Quiet Wing Corp modification kit that received certification in 2005.

Blended winglets, which stand approximately 8 feet tall, were standard on the 737 NG since 2000 and can be retrofitted on 737 Classic models.

They improve fuel efficiency by up to 5% through lift-induced drag reduction achieved by moderating wingtip vortices.

Split Scimitar winglets produce up to a 5.5% fuel savings per aircraft compared to 3.3% savings for the blended winglets.

Here's a quick rundown of the different winglet types:

The Boeing Business Jet (BBJ) series offers a range of options for those looking for a high-end corporate jet. The BBJ1, based on the 737-700, has stronger wings and landing gear from the 737-800, and increased range through extra fuel tanks.

The BBJ1 was first rolled out on August 11, 1998, and flew for the first time on September 4. It's a significant upgrade over the 737-300, with additional features that make it a top choice for corporate travel. Boeing launched the BBJ2 on October 11, 1999, based on the 737-800, which is 19 feet 2 inches longer than the BBJ1, with 25% more cabin space and twice the baggage space.

The BBJ3, based on the 737-900ER, has 1,120 square feet of floor space, 35% more interior space, and 89% more luggage space than the BBJ2. It's a game-changer for corporate travel, with its auxiliary fuel system giving it a range of up to 4,725 nautical miles.

Boeing offers cargo conversions of 737-300, resulting in the 737-300F or 737-300BDSF, depending on the company that performed the conversion.

A large cargo door is installed in the left front fuselage of the 737-300F, replacing cabin windows with metal plugs.

The Boeing Converted Freighter program (BCF), also known as the 737-800BCF program, was launched by Boeing in 2016.

The first 737-800BCF was delivered in 2018 to GECAS, which is leased to West Atlantic.

Boeing has signed an agreement with Chinese YTO Cargo Airlines to provide the airline with 737-800BCFs pending a planned program launch.

The Boeing Business Jet (BBJ1) is a business jet version of the 737-700, with stronger wings and landing gear from the 737-800.

It has increased range over the other 737 models through the use of extra fuel tanks. The first BBJ rolled out on August 11, 1998, and flew for the first time on September 4.

The BBJ1 is externally the same as the standard 737-700, making it a great option for those who want a corporate jet that doesn't stand out from the crowd.

It's worth noting that the BBJ1 was later replaced by the BBJ2, but it remains a popular choice for business jet enthusiasts.

The BBJ1 has a range that's increased due to the extra fuel tanks, making it ideal for long-distance flights.
