I have noticed on the Halifax Airport website (www.hiaa.ca) that there is a flight today (April 1st) on North American Airlines arriving from what the website says is 'NAS Chambers' at around 2030 and then departing at 2245 to 'Rotuma Island'. The Flight is North American 2170 and according to Flightaware.com it is operated by a 757-200 and orginated in Norfolk bound for Halifax but unfortunately there are no details on the departure from YHZ which appears to be using the same flight number. Does anyone know what the purpose of this flight is? It's not the first time I have seen it on the YHZ airport flight information list...I have seen the same flight with the same origin / destination in recent weeks. Looking for any information!
