Editing Avro Canada CF-105 Arrow (section)

===Scale models===

Between 1954 and 1957, nine Avro Arrow models, scaled at one-eighth size or about {{convert|3|m|ft|order=flip|0}} long, are believed to have been launched, using rockets, over [[Lake Ontario]] from Point Petre in [[Prince Edward County, Ontario]] as part of the process for testing the hull design. (Two others were launched in Virginia.) They travelled at supersonic speeds as onboard sensors sent data back to shore.<ref>[https://www.thestar.com/news/gta/2013/01/03/avro_arrow_lost_models_draw_arrowheads_to_search_lake_relentlessly.html Thestar.com]<!--Date of retrieval?--></ref> After many attempts to find the models, a new search was started in late July 2017. The Raise the Arrow project, operated by OEX Recovery Group Incorporated, was a joint venture by several companies, the Canadian Coast Guard and the Royal Canadian Military Institute. A Thunderfish autonomous submarine, equipped with an AquaPix interferometric synthetic aperture sonar, was being used to survey the relevant area of the lake bottom.<ref>[http://www.cbc.ca/news/canada/toronto/avro-arrow-models-lake-ontario-1.4225591 CBC.ca]<!--Date of retrieval?-->; [http://globalnews.ca/news/3633062/mini-submarine-launched-in-lake-ontario-to-uncover-the-avro-arrow/ Global News online]<!--Date of retrieval?--></ref> Any scale models found will be restored and displayed at the [[Canada Aviation and Space Museum]] in [[Ottawa]] and the [[National Air Force Museum of Canada]] in [[Trenton, Ontario]].<ref>[https://www.theglobeandmail.com/news/national/submarine-mission-aims-to-recover-avro-arrow-jet-prototypes-from-lake-ontario/article35728162/ ''Toronto Globe and Mail'' online]<!--Date of retrieval?--></ref>
