Joe said evenly, "But even if Ivan Ivanovitch, or whatever you claim his name was, didn't invent flight of heavier than air craft, the glider was flown variously before 1900, including Otto Lilienthal in the 1890s, and was designed as far back as Leonardo da Vinci."
The Sov-world colonel stared at him for a long moment, then gave an inane giggle. He stepped back and flicked Joe Mauser a salute. "Very well, captain. As a matter of routine, I shall report this use of an aircraft for reconnaissance purposes, and undoubtedly a commission will meet to investigate the propriety of the departure. Meanwhile, good luck!"
Joe returned the salute and swung a leg over the cockpit's side. Max was already in the front seat, his semaphore flags, maps and binoculars on his lap. He had been staring in dismay at the Sov officer, now was relieved that Joe had evidently pulled it off.
Joe waved to the plane ahead. Two mechanics had come up to steady the wings for the initial ten or fifteen feet of the motorless craft's passage over the ground behind the towing craft.
Joe said to Max, "did you explain to the pilot that under no circumstances was he to pass over the line of the military reservation, that we'd cut before we reached that point?"
"Yes, sir," Max said nervously. He'd flown before, on the commercial lines, but he'd never been in a glider.
They began lurching across the field, slowly, then gathering speed. And as the sailplane took speed, it took grace. After it had been pulled a hundred feet or so, Joe eased back the stick and it slipped gently into the air, four or five feet off the ground. The towing airplane was still taxiing, but with its tow airborne it picked up speed quickly. Another two hundred feet and it, too, was in the air and beginning to climb. The glider behind held it to a speed of sixty miles or so.
At ten thousand feet, the plane leveled off and the pilot's head swiveled to look back at them. Joe Mauser waved to him and dropped the release lever which ejected the nylon rope from the glider's nose. The plane dove away, trailing the rope behind it. Joe knew that the plane pilot would later drop it over the airport where it could easily be retrieved.
In the direction of Mount Overlook he could see cumulus clouds and the dark turbulence which meant strong updraft. He headed in that direction.
