I have a question:

I have always wondered how fast air is travelling out the business end of lets say a 777 GE90 engine???

A British Airways 747-400 with RR power pushes back at 2105GMT at LHR heading to ORD, climbs to FL370. flies at typical cruising speed. A United 777-200 with P&W power pushes back at ORD at 2052GMT. Climbs to FL380 and proceeds to LHR at typical cruising speed.....

Questions that people will ask given this information:

1. The obvious, where will they pass? (responses welcome)
2. Who has prettier flight attendants?
3. Who is eating the better meal?
4. Which flight crew is paid better?
5. Have either of these airplanes had a tailstrike?
6. Can I jumpseat on either of these airplanes?
7. When will NW get rid of their DC-9s/10s?
8. Which airline is paying too much to ground crews?
9. Can I open the cabin doors in flight?
10. What is the pressure of a lav flushing?

Haha Startvalve, that's hilarious.
But seriously, I actually have wondered, as UAL747 asked, how fast the exhaust from a typical jet engine is travelling upon exit from the jet. I once asked a professor about this, and got an answer of around 2000 ft/sec, if i remember correctly, which is obviously extremely fast. I could probably look in a fluid dynamics book and get an answer, or just run some quick equations, but it's winter break, and my books and my brain are thankfully 2500 miles away.

I'm watching Jeopardy. The category is worst Madonna songs. "This one from 1987 is terrible".
