That Canada could have been flying F-14 Tomcats.

Apparently during the Iran Hostage taking, the US having cut off all ties with Iran meant that Iran would have huge problems with getting spare parts, and apparently the aircraft were offered to the Canadian Airforce (before we took delivery of our CF-18s) for pennies on the $.

However the Canadian Embassy staff in Tehran were helping get US citizens out of Iran through the Canadian Consulate, which Iran didn't take too kindly too and the deal fell through.
