Re: Douglas DC-9
Unlike the competing but slightly larger [Vous devez être inscrit et connecté pour voir ce lien], which used as many [Vous devez être inscrit et connecté pour voir ce lien] components as possible, the DC-9 was an all-new design.
The DC-9 features two rear fuselage-mounted [Vous devez être inscrit et connecté pour voir ce lien] engines, relatively small, efficient wings, and a [Vous devez être inscrit et connecté pour voir ce lien].[Vous devez être inscrit et connecté pour voir ce lien]
The DC-9's maximum takeoff weight was limited to 80,000 lb (36,300 kg) for a two-person flight crew by [Vous devez être inscrit et connecté pour voir ce lien] regulations at the time.
[Vous devez être inscrit et connecté pour voir ce lien] DC-9 aircraft have 5 seats across for economy seating.
The airplane seats 80 to 135 passengers depending on version and seating arrangement. (Note: DC stands for Douglas Commercial.[Vous devez être inscrit et connecté pour voir ce lien])

The DC-9 was designed for short to medium routes, often to smaller airports with shorter runways and less ground infrastructure than the major airports being served by larger designs like the 707 and DC-8.
Consequently, accessibility and short field characteristics were called for.
The tail mounted engine design facilitated a clean wing designs without engine pods, which had numerous advantages.

First, [Vous devez être inscrit et connecté pour voir ce lien] and [Vous devez être inscrit et connecté pour voir ce lien] could run the entire span of the wing, unimpeded by pods on the leading edge and engine blast concerns on the trailing edge.
This simplified the design, improved airflow at low speeds and enabled lower takeoff and approach speeds, thus lowering field length requirements and keeping wing structures light.
The second advantage of the tail-mounted engines was the reduction in foreign object damage from ingested debris from runways and aprons.
Third, the absence of engines in underslung pods provided a reduction in ground clearance, making the aircraft more accessible to baggage handlers and passengers.

Turnarounds were simplified by built-in airstairs, including one in the tail, which shortened boarding and deplaning times.

The first DC-9, a production ship, flew in February 1965. The second DC-9 flew a few weeks later and entered service with [Vous devez être inscrit et connecté pour voir ce lien] in late 1965.
