UPDATE - 4/5@1:38PM: Here are some of DJ_Carter's comments regarding the radio-edit of Headlong Flight that he listened to:
... The opening chords sound almost EXACTLY like a heavier version of Bastille Day. ... There's some Bastille Day rhythms, a more raw guitar tone that sounds less polished and more Hemispheres-y, an absolutely bone-shattering drum break in the middle that sounds like a modern version of Neil's break in By-Tor, and some really audible and fun shifts in the structure of the song, a la the transitions in Natural Science. If I had to encapsulate the sound in just a few words, it would be Caress of Steel crossed with Vapor Trails. Headlong Flight doesn't feel as heavy as BU2B; it's very much Vapor Trails-y, but with much more tasty bass. Truly, the bass in this song is killer. I think we can count on seeing a lot more of the Leave That Thing Alone live solo stuff on this record. ... One thing that was really encouraging about this track was the fact that Neil's drumming was very fast in certain places. BU2B was ... heavy but plodding, not challenging or rhythmically complex. Headlong Flight is totally different. This is Neil at his best, and the break I mentioned earlier feels like his classic fills. There is indeed a guitar solo, towards the end of the track. But it's a solo in the sense that Alex's solo from Caravan was a solo. He's shredding, no doubt about it, but it isn't like a Freewill type of shredding that has a pattern and a resolution. Very frenetic and exciting, though! ...

UPDATE - 4/5@8:00AM: I have a few more details regarding the track lengths of the various edits from reader DJ_Carter. He let me know that the album version of Headlong Flight runs in at 7:20. The original length of the radio-edit of the track was 5:20, but once it was confirmed that it would be the first single they produced another, shorter version that clocked in at 4:50. He was played both of these cuts (the 5:20 and 4:50 versions) but couldn't tell any significant difference.
