Is it the highest of any commercial jetliner ? My back-of-the-envelope calculations would suggest about a .38 thrust to weight ratio. That is assuming the RR RB211-535E4B gives around 42,000 lb thrust (SLST) at a MTOW of 220,000 lb. I'm not aware of anyone who actually bought that configuration, though. Oh, and on their acceptance flight tests, (I got to fly one on a 737-400 once) these babies are *empty* and climb like homesick angels. I have seen VSIs pegged (6,000fpm+). >I've also heard that there is a boeing-internal video of it >during tests doing an [almost?] straight vertical climb. I've never seen it, but then I don't do any flight test stuff. >What are the facts here ?
