talking about teapots reminds me of a story telling of a famous Australian Aviator who lost an engine (3 eng. a/c) on a oceanic crossing ...... sometime later no. 2 started loosing oil at an alarming rate ..... his engineer filled a flask with oil - climbed out numerous times to the engine and topped up the oil resevoir ...... some eleven hours later the aircraft landed safely .....
I suppose the motto of the story being .... if you don't take a teapot then a flask is a must .....
ps. a true story I assure you ..... the guy was knighted for his Aviation exploits as I recall ......
