i have a funny story, itsd fairly similar but the other way around
when i was explaining about WFP to a old boy, he said he didnt like the sound of it, as he worked on comercail aircraft all his life as a engineer and didnt want to be reminded of them times
i didnt get it
well it turns ou he thought i would have a generator to power the pump and it would be real loud and sound like a aircraft engine
i did laugh at that 1
