Yeah just noticed that in the graphic above, and I'm guessing its final descent rate of nearly 31,000 fpm!

So was its IAS 544kts like the post above suggests? Will check to see what its cruising speed is at alt.

But even if groundspeed, of 440kts, its IAS speed would be what, 460 - 480kts (seems excessive for a 737 in the cruise, will have to look it up).
