Wash thy mouth forthwith Ranger, the 900EX is indeed a superb machine
We had a series of demonstration flights between the 900EX and the G-IVSP, most from Aspen to St. Maarten and from OKC to various destinations in the UK and Europe.
Primary deciding factor was Aspen performance on summer days and whether either aircraft had the capability of going to London non-stop from Aspen.
The 900EX was capable of non-stopping Aspen to London in the winter*, the G-IVSP was not, plus the boss liked the idea of three engines for Pacific crossing to China and Singapore, therefore, we bought the 900EX.
Both aircraft are excellent performers and I would have been happy flying either one. The Falcon was a nicer handing machine than the Gulfstream, but in truth that was not a deciding factor.
* Going non-stop to London from Aspen greatly depended on the OAT at Aspen and good VMC weather both at Aspen and London. Plus the expected tail winds of that time of year. To be honest, I have forgotten the minimum OAT we needed at Aspen. However, in the dead of winter on early clear mornings, it would usually be low enough to plan a 07:00 (local) departure.
Once the boss showed up for a 07:00 departure for London at 10:00 and guess what, hello Bangor. He took it in good humour however, knew it was his fault.
