I have heard the story of "Take off power" vs Takeoff Power", too, but it was in relation to a military mishap. The only bad Air Canada DC-8 accident from that period that comes to mind is the 1970 crash of of AC621 at Toronto. In that accident, the F/O deployed the spoilers before touchdown instead of arming them. This resulted in very hard landing and a go-around was attempted. Unbeknownst to the crew, the number four engine had hit the runway and broken off. Leaking fuel caught fire and the resulting explosion caused most of the right wing to break off. The DC-8-63 crashed about three minutes after the initial mishap, killing all 109 people onboard. The CVR revealed that the spoilers had been deployed when the Captain asked for them to be armed. There were two other hard landings of DC-8's (Alitalia and Icelandic, I think) caused by premature spoiler deployment not longe after this accident. Eventually, an AD was issued to modify the spoiler control system. As far as engine reversing in the air goes, there was an incident in the early 1960's involving an Eastern DC-8 in which ability to reverse the two outboard engines help the crew recover a steep dive that had been caused by an upset. In an ironic twist, a member the flight crew involved in that incident later died in the crash of another Eastern DC-8 near New Orleans. That crash was the result of an uncontrolled dive, possibly caused by a trim problem. Reverse thrust had been used to help pull out of the dive and the manuver (sp) was almost successful.
