The main reason why propulsion formed a hurdle in the quest to be able to fly around the year 1900 was that **engines supplying the required power were too heavy**. At that time, the weight-to-power ratio of available engines was not sufficient to allow for powered flight, as a lightweight engine capable of providing enough thrust was crucial for sustaining flight.
