TW,
Sealand did not buy OKY.......Sealand was bankrupt at the time.
CHC,actually Canadian Helicopter Corp, bought Sealand, Oky, Ranger, Maple Leaf, Toronto Helicopters, etc, etc.....
CD formed CHC and went to Toronto and convinced some Bay St. suits that if they loaned him the cash, he could build a successful helicopter company.
They bought into it and as they say, the rest is history.
