I recall in my past at Lake Keepit in Australia on one Friday doing 78
tows in PA25-235 and the next Friday I broke that record and did 82
tows. We were well organised on the ground with me dropping the rope
and the next glider would be ready to go and a ground crew would hook
on the next rope onto the Pawnee.

This is not to you in particular, but queueing theory suggests that
maximum throughput of a queue occurs when the delay for each "customer"
in the queue approaches infinity.

So, how many gliders were typically waiting to be launched. and how long
did they have to wait?


I much prefer days like we had on Monday. There were 13 gliders in the
queue, but once they were all launched (and ten of them disappeared into
the distance) the towplane spent large amounts of time sitting on the
ground doing nothing.
