"Splutter, splutter. Yes - we're off - we're rising. But why start off with an engine like that? But it smooths out now, like a long sigh, like a person breathing easily, freely. Like someone singing ecstatically, climbing, soaring - sustained note of power and joy. We turn from the lights of the city; we pivot on a dark wing; we roar over the earth. The plane seems exultant now, even arrogant. We did it, we did it!"
