The -100 is by far the shortest 737 ever built — nearly 9 m shorter than the -800. Its tiny size and very short cabin make it unmistakable beside any later variant.

Specifications

Figures are for the representative variant described above; marks differ. See how AircraftIQ sources figures.

History

Lufthansa was the launch customer, introducing the type in February 1968. Only 30 were built as airlines quickly preferred the stretched -200. The JT8D engines mounted directly under the wing — unlike later CFM56-equipped variants — gave the nacelles their distinctive flattened underside.

Variants

No formal sub-variants; all 30 were to the same basic configuration.

Where you'll see it

All passenger examples retired decades ago; none are believed airworthy as of 2026.
