An animal conservation project close to my heart is the rehabilitation of rescued Gibbons from the pet trade in Southern Thailand for eventual release in the wild at National Parks in the North, repopulating them there, where they were once indigenous, but were hunted to extinction.
I provide the transport link, avoiding a stressful 3 day road journey with a sub three hour non-stop flight.
The Jetprop is the ideal aircraft for this mission.
A kind donor commissioned custom cages to fit in the rear of the aircraft.
I just completed the latest mission airlifting three hopeful families for a chance of freedom.
Gibbons are primates. One of my wittier friends commented that the Gibbons in the back were probably more qualified to fly the aircraft, than the monkey in the left seat.

A well-known resident pilot of the IOM did a line in transporting pedigree rams, he could carry three at a time in a PA32 in specially made crates.
This is really heartwarming
Out of interest, how do the gibbons react to flying?
@eal, do you protect them against the noise in any way?

I have transported around 30 adults and infants to date. Except for one inconsolable female they are great passengers. Very vocal – deafening in fact, until we take off, and then they are quiet for the remainder of the flight. We give them water if the flight is non-stop, and some of them like to play with it, often flicking it back at us.
They have a remarkable reach, so I have to be very careful as they like to grab hold of me when I pass by the cages.
Once ATC became aware of these flights, they have been super helpful, offering direct routing whenever they can.

One of the great advantages of a turbine, and especially the Jetprop is the low noise and vibration in the cabin. No need for any protection, other than my wish to gag them sometimes when taxiing in, and they are making themselves heard! Lol.
They are not sedated either.
In the early days, various tower controllers quizzed me about the distinctive background noise over the radio.
Overall a unique flying odyssey that I value greatly.

A very valuable use of a plane!
That “chimp” has a higher IQ than a lot of airport employees, especially the 9mm carrying ones
