'''' The Car Ferry loads made a single flight before being unloaded. A different load would normally be taken for the return flight..
We carried a lot of cars over the years, all clamped down with chains, as mentioned. A loaded Bristol Freighter sis not have (quite ?) the same T/O performance as a B747.
I had ONE highly magnetic car. It showed that the QDM of the R/W at Le Touquet had altered by 10 degrees since we had landed a few minutes earlier ! ( The weather was clear, so we continued.)
Goldfinger's car would not have had THAT effect.
