In the same vain as Tilt and Gain (oh, that rhymes).
Over Bos at 25K, time for a sandwich and drink to break the 4 hour monotony of circles.
Reach into butty box precariously jammed between cockpit wall and bang seat, to discover sandwiches (without crusts, nice) cut into small cubes (handy), Benson's crisps (not so much), crushed to snowflake size (leave 'em), a choccie bar (valuable commodity and equivilent to 6 beers later) and a can of coke. From feeling the can you could tell it was at about 1500psi.
Pilot: don't open the .....
nav: (bang....fizz.....drip, drip).... coke?
I guess we're RTB then.
There's another story of a FJ mate opening their box (!) to find a pot noodle. Useful. But it wasn't me so I aint tellin' it.
Apparently it tasted just the same without the water....
