Taiwan is funding Our Airline
A simple fact - the Taiwan government has a budgeted funding account for the 'Our Airline' operation and is not allocated as an aid project. Also the Nauruan government has sent a former Speaker of the House to Taipei as their Consul. He is very well respected in diplomatic circles and a very, very nice bloke. They are protecting their future flow of aid funds and ensuring the airline is also funded for the short term at least.
Finally, if you knew the salary levels of the ON 'management team' you'd know why they need the might of the Taiwan economy behind them. In Micronesia we are paid a reasonable salary for our efforts.
