Just had someone telling me that aircraft descend at a rate of 300'/second. 'No they don't' 'How the #$%^ would you even know' 'Well the items floating around as gravity would no longer apply would be a fairly reasonable hint.'
Yet more trolls on @quora I didn't know this but apparently you can delete someone else's comments while you yourself reply to them that are not longer visible.
I had to LOL at this piece of 'advice' I can only imagine someone trying this.
