If I was a professional pilot I would be quite happy to have my coffee or tea or any liquid dispensed in a kids cup with the non spill lid. Why, in the light of serious expense involved in cleaning a coffee spill in electronically dominated cockpits, is this not the norm? It means one can drink during turbulence without spilling onto one's shirt and would alleviate at a stroke almost any possibility of causing problems on the flight deck. The cost, in real terms, of providing disposable versions would be in pennies. Dry cleaning bills less. I am sure a good Industrial Designer could produce a Street Cred version to satisfy flight deck egos!
