Following the completion of flying tests performed by the prototype, the British government exercised considerable indecision over the fate of the programme. In addition to the prototype, a further two Princesses ("G-ALUO" and "G-ALUP") were under construction, but these would ultimately never fly. While a decision from the government was effectively pending, the three existing aircraft were placed into storage, being cocooned and retained, one at Cowes and two at Calshot Spit; it had been hoped that work on the programme would be restarted when a buyer was found.
