Tony smirked. He would have been quite surprised if the man hadn't needed a demonstration first, and Tony was happy to take the Iron Man out for a spin. He clasped a hand on Wash's shoulder, grabbing a nearby glass of bourbon and finishing it off. The mostly empty bottle was nearby.
"C'mon. Viewing platform, and you'll see the genius that came before this most recent genius," he said, leading Wash upstairs to the luxurious living floor, passing by the kitchen, overstocked bar, and living room area to go to the balcony.
"What d'ya think, J, take it easy on him?"
"I'm quite certain you've already a method in mind, sir," Jarvis responded.
"You're no fun anymore, Jarvis," Tony shrugged and smirked, opening the glass french doors and stepping out onto the balcony. "Fire it up." Leaving Wash behind in a moment and then turning to give him a wink, extending his arms. After a moment a hidden chute opened on the side of the building and a large red and gold bullet exploded outwards, running the scan over Tony and then attaching itself to his body, extending out and enveloping his form until he was the Iron Man.
"Try not to wet yourself in anticipation of your own ride," he said, voice now relayed through the mechanized helmet. He took another step back, then egnited the thrusters, taking to the air. Flying came as naturally to him as walking, breathing, or drinking after all of this time, though he never forgot just how long and painful learning to control his gear had been, for him and his classic car collection.
He gave Wash a show, looping around the building a few times, soaring up as high as the City would allow him and then falling back.
Once the demonstration had given Wash a flavor of what he was in for Tony landed on the extension of the building, walking back towards Wash again. As he did the walkway came alive, relieving him of his Iron Man armor, which was quickly and effeciently removed and sent back to the Armor Hall to be readied for another round of service. By the time Tony reached Wash again, he was once more wearing only a set of finely tailored working clothes and the identification bands on his wrist.
"So. Interested in flying, Wash? Or do I need to find a test pilot who doesn't mind a lack of extra space in his machine?"
