Speaking of D.B. Cooper...

Your story reminds me of another true one )

Had been flying the P-51 and the relief tube was just a cone like you
describe. Used on many occasions and never had it freeze up.

Transitioned to the P-80 and on a early flight had the urge. Pulled
the cone out from under the seat and started to use and it rapidly
filled up which necessitated a rapid stop of flow with all of its
problems. Wiggled the hose around to see if it was pinched and still
had a full cone in my left hand. Flew to home plate that way and
retarded the throttle with my elbow and landed and taxied in. Crew
Chief jumped on wing and I said, you need to fix this relief tube.
It's clogged.

He took it an there was a little metal lever on the side which he
pushed and the cone drained on ramp. He then explained to me that in a
pressurized cockpit the relief tube had to have a valve in it or
cockpit pressure would bleed out relief tube.

During future uses of tube, I found that I could depress the lever and
the cockpit pressure going out would collect the liquid from about 6
inches above cone. Of course you had to be careful that your 'tool'
didn't get too close with the valve open or it could get sucked in.
Ouch! (

Now in my Mooney with 7 1/2 hours of fuel (built in fuselage tank) I
had a coffee can with a plastic lid. Worked fine every time )

I had to pee bad into one of this ice cream cones attached to a
ventura on the belly of a twin Beech once. Problem was, it was iced up
and the damned thing was blowing instead of sucking. Of course, once
you start....
