I received this today:-

There are still people in this company who think we weigh aircraft to find
out how much they weigh, not to calculate stresses. Of course we need to
know how much the thing weighs. How are we ever going to know how many
Thrust Pixies we need to get the thing off the ground if we don't know the
weight? Or should that be "Lift Demons"? Pixies have largely fallen into
disrepute - something about Bernoulli not being representative in
unbounded
conditions and cause and effect being transposed in the Newtonian model.

Many (most) Navy pilots claim that black air has no lift, which means they
can get all night in to supplement their daytime naps between meals. This
shows that Lift Demons are not nocturnal. Thrust Pixies may be what is
needed. OTOH, would they be any use in getting Air Force maritime patrol
aircraft to stop reaching "prudent limit of endurance" by 1400 Local every
Friday just after reporting a "possible intruder" submarine in the exercise
area, and not be restored to flying status till Monday am, while the ships
stay out over the weekend looking for the "intruder"? Is there such a
thing as a Thrust Demon for them?
