Three questions:

1. Do you find this to be:

A. Ordinary and of little significance.
B. A bit unusual
C. Very unusual
D. Extremely unusual and bad practice and worthy of scorn from ass-hat outsiders.

2. How often do you see two airliners on the runway at the same time, waiting for takeoff?

3. What do you consider a proper spacing for this situation.

Thanks in advance.

I for one am very disappointed. I was hoping the aviation world had finally got the memo about this: https://en.wikipedia.org/wiki/Drafting_(aerodynamics)

IKR? It's just like drafting except that the whole peloton in front of you farts at once very hard.

1. C
2. Not that I can recall, at least not when both were stationary (see next answer).
3. I don't believe I have actually ever seen it written anywhere, but generally accepted practice appears to be that one does not taxi into position until the preceding aircraft has started moving. At any rate, I don't see what the UA crew's hurry was, but whatever.

Sincere: Thanks

Snark: For Tlazolteotl‘s sake, please get this written into the appropriate acronym and regulation manual ASAP!

Footnote: Does your FCOM really have a chart of exhaust velocity vs distance…with “hard” numbers?

At any rate, I don't see what the UA crew's hurry was, but whatever.

Based on some documentaries I've seen on the intarwebs, it may have had to do with snacks.
