Luverly-grub on the ground is all very well, but if you had to partake of a lunchbox whilst flying en-route I thought you'd be interested in what we fliers had to endure whilst travelling out east in the late 1970's, as witness this lunchbox provided by civilian caterers at Khartoum in July 1979.
A couple of ropey rolls and two dead bananas - so awful I had to photograph it for posterity. Mind you it wasn't too bad because ISTR none of the crew had to be hospitalised afterwards!
