Pionair Ghana

[1970s Spotter]

ANOTHER Boeing 707/720 querie!

Anyone know anything of a company called Pionair or Pioneer Air Cargo based out of Ghana in the mid 70s?
They,as far as I can remember, operated an old United 720-022 N7216U in basic UAL colours.
I saw it at DUB in about 76, did it ever move?

Thanks
