If we could bring down airplanes with toothpaste that would be fantastic. Think of the financial savings: no need for Instrument Rating, written exams, coastal refraction etc..
Reminds me of the Infinite Improbability Drive in the Hitchhikers Guide to the Galaxy which was powered by tea, if memory serves.
Just issue all PPLs with a tube of toothpaste (with three stripes of course, can't be giving them too much power straight away) and you have instant IR CPL. Amazing. Why has the CAA not thought of this! I think we should be told.
