Both the Blues and the T-Birds fly a very tight formation. Which takes a lot of skill, I would certainly agree.
But the dynamics of such a formation result in a display which lacks the immediacy of either the Reds or the Patrouille de Frances' displays.
The whole razamatazz of the 'drive in', choreographed hand shakes with 'plane captains' etc pads out the display hugely. OK for the genpub, perhaps, but aircrew cringe at the "Flying Blue 2 in this great Texas sky is Lootenant Hiram B Chickensexer the third, a college letterman for track and field who graduated University of Whatville before gaining his wings of gold....
" stuff from the commentator. Whereas other displays speak for themselves...
Impressive flying? Indeed. Appropriate for a formation flying display? Perhaps not.
