I have asked Denis Gravel, LaSalle historian about the LaSalle airport and he confirms that there was such an airport on the land and prior to the golf course in the beginning of the 30s. There is an old map somewhere showing the airport and Denis will send it to me when he finds it. As far as some photos are concerned, these may be harder to find but hopefully some will turn up sooner or later. Denis also says that a LaSalle citizen told him that light aircraft used this airport.
This is a new and interesting subject and I hope we can discover more information on this airport where Buzz Beurling started his interest in aircraft. Buzz died at age 26 in 1948 therefore he was born in 1922 and he must have been very young when he started flying.
