Back in July, the story of the ill-fated Air Canada flight #621 that crashed on a go-around from YYZ 34 years ago made the news. As I read through the details of this sad incident, I remained puzzled by one thing: Why did the captain choose to execute a go-around after the aircraft hit the ground so hard following spoiler deployment by the FO some 60 feet above the runway?
The transcript is online at http://aviation-safety.net/cvr/cvr_ac621.shtml.
In a previous discussion, someone pointed out that ATC may not have had a view of the DC-8-63 when it hit hard and lost engine #4, so the crew might not have realized what happened right away. But I would think that with such a hard drop onto the runway, the impact itself would have been cause for not going around. And the other thing that puzzles me is the suggestion that there wasn't enough runway to stop the aircraft following impact. Arriving from Montreal, wouldn't the aircraft have been relatively under-fuelled? And besides, runway 32 is over 11,000 ft. in length. Did the DC-8 hit the runway at the halfway mark?
There are lots of things that I can't reconcile when trying to create an image of those critical moments. I'd appreciate any additional thoughts/input.
(BTW, a book is apparently going to be released next year, on the 35th anniversary of the accident. If anyone knows the release date, publisher, etc., please reply. Thanks.)
