It would be hard to imagine the amount of smoke that this Concorde engine could produce.

The engine pictured above is mounted on to a lorry, but this is for transportation or static running only. Due to the high level of fuel consumption, the onboard fuel tank gives approx 5 minutes of running (120Ltr), so extended runs would require a fuel bowser nearby.

The engine is started by a separate air producing turbine (APU).
