Notable jets, without APUs... besides the DC8 were -
B-707 B-720, Comet, Caravelle, CV880/990, and the ones that I forgot
The philophy was that initially, all these airplanes operated from well equipped airports... lighter airplane...
The 707/720s, DC8s, CV880/990 required a 115V AC
ext power cart...
They needed an air cart for air conditioning and engine start...
The Comets and Caravelles required a 28V DC ext power cart, and 115V DC for start, air conditioning unit cart.
Happy contrails -
