Recently I have been haunting the Provincial Archives New Brunswick here is Fredericton. I came across some crash images of CF-KCG, Conair #615, which I have posted to its aircraft page.
Also, a mystery has been solved! FZTR and FZTS: The Mystery page, which now reads SOLVED! Barry McLeod had alerted me to a very interesting page run by the Stoltzfus family of Coatesville, Pennsylvania, who had purchased four Avengers in 1957. After a series of emails regarding N7028C and N4173A, Ken Stoltzfus decided to order the Certificate of Registration for N4173A. The previously unknown BuNo was finally revealed as 85904 and the BuBo for N7028C was confirmed as 53775.
Read about it on the revised mystery page.
