Never saw the Blue Angels. But the T-birds came to my city last year and finally got to put the Irish tricolour on the F16s. They opened their European tour at my local airshow. They were brilliant, impressive. But I have to say the Silver Swallows were better.
Sorry

What do mean you never heard of the Silver Swallows?
Well fair enough. They were the aerobatic team of the Irish Air Corps. Four Fouga Magisters flying formations as tight as anything you would see with the Blue Angels. All the more impressive is that there were no ejection seats in the Magister. There is a youtube video of them and the display was impressive considering our Air Corps had only six Fougas. Sadly they are now disbanded as the aircraft has retired. The Air Corps now operate PC9s. Which is crazy. Have you ever heard of airforce going back to propellor driven aircraft from jets.

But patriotism aside, having seen the T-birds, the Frecce Tricolori, Patroulle de France and the Red Arrows I have to say it's got to be the Silver Swallows

Well Ok the
Red Arrows. I said the
Red Arrows (Damm those Brits)
But I would love to see the
Blue Angels. I might change my mind then
