I spent 2 years flying around the world on An124 charters Air Foyle.
They
are very noisy aircraft although I did have my own cabin so it was
quite
comfortable aside from the noise. The worst thing is that you cannot
put
toilet paper in teh toilet after you have used it, it goes in a waste
bag
hanging by the sink. I hated those toilets.

Don't complain!

The soviet AWACS (a modified IL-76 transporter) has no toilet at all,
the crew must use a bucket.
(In the last minute extra electronics were added to the design and they
needed to find another 1,5 cubic meters of rack space, so the toilet
went down the loo.)
