During Operation Market Garden, the attempt to seize a bridgehead across the Rhine in the Netherlands, the 704th dropped supplies to allied troops near Nijmegen. It struck lines of communications during the Battle of the Bulge. During Operation Varsity in March 1945, it supplied ground and airborne troops near Wesel.

Q: Question: How old was the engineer when his invention was tested for Evel Knievel? Passage:ABC's Wide World of Sports was unwilling to pay the price Knievel wanted for the Snake River Canyon jump, so he hired boxing promoter Bob Arum's company, Top Rank Productions, to put the event on closed-circuit television and broadcast to movie Investors in the event took a substantial loss, including promoter Don E. Branker, as well as Vince McMahon of what was then called the World Wrestling Federation. Arum partnered with Invest West Sports, Shelly Saltman's company, to secure from Invest West Sports two things: first, the necessary financing for the jump, and second, the services of Saltman, long recognized as one of America's premier public relations and promotion men, to do publicity so that Knievel could concentrate on his jumps. Knievel hired subcontractor and aeronautical engineer Doug Malewicki to build him a rocket-powered cycle to jump across the Snake River, and called it the Skycycle X-1. Malwecki's creation was powered by a steam engine built by former Aerojet engineer Robert Truax. On April 15, 1972, the X-1 was launched to test the feasibility of the launching ramp. The decision was then made to have Truax build the Skycycle X-2 and have it take off and fly more like a rocket than a motorcycle.

A:
On April 15, 1972, the X-1 was launched to test the feasibility of the launching ramp
