At Old Rhinebeck Airdrome in Red Hook, New York, sits one of the premier collections of vintage aircraft in the United States. Director of Maintenance Mark Mondello is one of the key people ...

A bold collaboration aimed to bring research to reality could rewrite the rulebook on sustainable energy. Advanced Innovative Engineering (AIE), the leader in high-performance rotary engines, is ...

Perfectly tuning the heat range of an engine's spark plugs is something of a dark art to all but the most well versed tuners and the engineering egg heads at automotive OEMs. Getting the spark plug ...
