Sorry Chris, I didn't say that, and it's not correct. As correctly stated in the article in The Economist:
The apex where the two lines intersect—where the minimum and maximum safe speeds are the same—is known euphemistically as “coffin corner”.
- it is the top of the load factor vs Mach curve, where low speed buffet becomes high speed buffet, at 1g. For the A330 that is at about M=0.82.
