Production and operation

The first Superfreighters, with a longer - 42 ft 3 in (12.88 m) - hold than the earlier Mark 31, were delivered to Silver City Airways in spring 1953 and were used on cross-channel services to Europe. One example was converted to a 60-seat all-passenger "Super Wayfarer".[1]

The Mark 32 could carry 20 passengers instead of 12 in the smaller Mark 31 Freighter, and three cars instead of two in its air ferry role.[2]

The Superfreighter was distinguishable from the earlier Freighter by having a longer nose, in which the extra car was carried, and a fin fillet as well as rounded wingtips.

A British United Air Ferries Superfreighter appears in the 1966 comedy film That Riviera Touch as the means by which Morecambe and Wise travel abroad with their car. The aircraft also appears in the 1965 film "Hysteria".

gollark: 2 + 2 = 4 -1 = 3 quick maths
gollark: 128 iterations per grid, 1000 iterations total, 16x16 grid, can't even get any with Conway's game of life rule which fill >1/3 of the cells at the end.
gollark: I should try adjusting the iteration count.
gollark: Maybe if I set an actual threshold rather than a ratio it'll be better.
