English "Microlight Instructor" and hackgineer Andy Tyler, age 35, father of 2 built a pulse jet engine out of instructions he got off the internet and attached it to a shopping cart he retrieved from a river. The liquid fueled engine glows red hot at temperatures up to 600 C. - hot enough to require a heat shield between the engine and the driver.
