Accidents and incidents

* On 27 August 1931, A Sikorsky S-41, NC41V of Boston-Maine Airways crash landed in while making the run between Halifax (N.S.) and Boston (MA). After clinging to the sides of a partially inflated life raft in rough seas for two hours, the 12 survivors were rescued by the ''F/V Nova Julia'', a mackerel seiner out of Gloucester MA, captained by Capt. Leo Favaloro. There was one fatality. Seventy-year-old Edward Bamwell was assumed trapped in the wreckage as it disappeared beneath the waves just a moment after he gallantly allowed one of the three women passengers to precede him to the waiting raft. The Sikorsky had only been in service one month. Heavy fog was cited as the cause of the crash. The S-41 was repaired and reregistered as NC60V.United States Civil Aircraft Register http://www.airhistory.org.uk/gy/reg_N32.html * On 28 October 1931, Col Thomas C.
