There were a few historic US military helicopters that strutted, or is that rotored?, their stuff at Thnder over Michigan in an impressive display of mobility and maneuverability.
There was a UH-1 Huey helicopter in medevac livery.
There was not one but two AH-1 Cobra gunships:
They were quick dancing around the sky, and both had rocket pods attached that they "fired", creating flame and smoke for effect.
So maneuverable, they could stop on a dime, whip around and give you 9 cents change.
There was a
OH-58 OH-6 helicopter that showed how maneuverable a little bird could be.
And there was a UH-1 in troop transport configuration.
It was quite an impressive display, and more helicopters were to grace the show later on.
