Hmm, someone asks if I want to get paid to go for a 2 hour flight on an $18,000,000 business jet, what do I answer? HECK YES!
Here's some pics, taken from my phone so they are terrible.
This thing is a ROCKET! We were taxiing, I was chatting with my co worker, who was facing backwards (the tail). I noticed us turning onto the runway then all of sudden WHOOSH, shoved to the back of the seat. Both of us were shocked at how quiet it was: we could hold a conversation at normal level sitting across the aisle and club from each other, at full throttle.

Next thing you know, he's hanging from his seatbelt as we climb out. Took no time to altitude. This was over Oklahoma I believe.

Passed a Southwest 737, we were at FL410, I guess it was down around FL360. It's hard to see, but it's near the center, slightly off the right.

This was our flight, we followed the dotted line back

This was one fast, high, and cold office 8-)

Thats all I have for pics. As we returned, the pilots were checking some stuff so they were diving (literally, at least 30 degree nose down) and deploying gear, spoilers, etc. The speedbrakes are interesting. When deployed, you don't notice much beyond a little vibration and a slowing sensation, but when retracted the lift gradient is intense.
We got really slow, nearly stalled, then sped up. My co-worker, who flies, went up to talk to the pilots for a minute, then came clambering back and quickly buckled his seat belt and goes 'They're gonna do a stall'. My seatbelt was on (the seatbelt sign wasn't, go figure

All in all, a good day. Sorry for the crappy pics, if I had more than 10 minutes notice I could have brought a camera. Although that is one nice thing about a biz jet. 10 minute heads up, go to the hangar, board the plane and go! No taking off shoes* (*I did have to take off shoes to not scuff the carpet

Hope you've enjoyed!
