Am guilty of rolling jaffas (round balls of chocolate with hard flavoured coatings) down the sloped wooden floors of the pictures when I was kid though (as Wayne mentioned)
TPBM will tell us a weirder name than Jaffa for a chocolate (and what it means if they know)...
Wayne, they couldn't see over the hood, only out the sides, so they had to go down the runway zigging and zagging to get into position for the take-off.
