Here's a THINK ONE from a CREW
Some time back we blew the electric lines onboard due to a noncompliant water heater then on the heaters were taken away and Vaccum Flask/Thermos were rolled in...
Cap asked for a cup of hot water and the what i heard was ... "Hot Water surely is there but it's cold now.... do you want me to put the flask in the oven..... can you do that..... if you want I can try"
Silently we reviewed our SMOKE memo procedures.....
