Para um exemplo histórico:
No 22 de novembro do 1968, um DC-8 que voava de Tóquio-Haneda para San Francisco acidentalmente atingiu a pista em seu destino um pouco e acabou na Baía de San Francisco.

Os passageiros e a tripulação 107 a bordo, nenhum dos quais se feriu, evacuou a aeronave em cinco dos sete botes salva-vidas da aeronave:
Two liferafts were stowed in ceiling compartments over the aisle adjacent to rows 1 and 2.
[...]
Five 25-man liferafts were stowed in ceiling compartments in the aft passenger compartment. Three of these were in the area of the over-wing exits over the aisle seats at rows 12 and 14 and two in tandem were over the aisle at row 3l, the last row of seats, and just aft of this row. [Page 22 of the report, numbered as page 20.]
The two forward stowed liferafts were removed from their compartments. One was launched at the main door and the other was launched through the forward service door.
Two of the four rafts stowed in the over-wing area were utilized. One was launched from each wing. One of the rafts stowed in the aft portion of the fuselage was carried forward and launched over the right wing. All of the wing-launched rafts were deployed from the leading edge of the wing.
Although some of the tourist-class passengers evacuated from the forward doors, generally the first- class entered the two forward rafts, while the tourist passengers entered the raft at the left wing and one of the rafts at the right wing. The remaining raft on the right wing was occupied by the captain and JAL employees.
From the passenger and crew statements, it was estimated that 29 passengers (no crewmembers) evacuated through the forward left door; 16 persons, including the flight engineer, navigator, and a stewardess, evacuated through the forward service door; 28 evacuated from the left wing, including at least two stewardesses and three JAL male employees; 25, including the first officer and a stewardess, occupied the inboard raft on the right wing; and nine, including the captain, purser, and two stewardesses, occupied the outboard raft on the right wing. [Pages 23-24 (numbered as 21-22).]
(Minha ênfase, e os passageiros e tripulantes que evacuaram das portas dianteiras e da asa esquerda também desembarcaram em balsas; é só que cada porta da frente [e a asa esquerda] tinham apenas uma balsa cada, então, para essas saídas, havia não há necessidade de distinguir quem entrou em qual jangada, ao contrário da situação da ala direita.)

Vôo a jato comercial: um voo JAL programado em um DC-8-62. Confira.
-
Após o 1945: ocorreu em novembro 1968. Confira.
-
Transporte de passageiros pagantes: 96 deles. Confira.
-
Capacidade mínima da aeronave, pessoas 50 ou mais: havia 107 a bordo, incluindo passageiros 96, e A Wikipedia fornece a capacidade máxima de passageiros de um DC-8-62 como 189. Confira.

Jangada (s) armazenada dentro da pré-implantação da cabine: nos compartimentos do teto acima do corredor (semelhantes aos do 737 na foto na pergunta do OP). Confira.
-
Jangadas, na verdade, projetadas e colocadas lá para esse fim: veja o marcador anterior. Confira.
-
Jangada (s) funcionou como previsto: bem, todos a bordo evacuaram para as jangadas sem ferimentos e ninguém se afogou. Confira.
