    Good point...I have recently heard those pulse engines are capable of faster than that too. Funny thing is, that trail only lasted about 30 seconds after I snapped the PIX.

    That is because a pulse engine is more efficient and maintains a more constant temperature.

    Then, there is the fact that the opening of the engine opens and closes very fast, meaning that instead of dumping a whole stream of exhaust in a constant flow, you have little bubbles of smoke that can clear faster.
