In the article in Flypast, Dave Thomas has warned that we are unlikely to hear the legendary Vulcan howl again when it does fly. When the Vulcan did a wing over at the end of the runway on full power, the howling noise (I presume from the intakes) was just incredible, and the thunder of the exhausts made it feel like the whole universe was vibrating. But the engines are very limited on cycle life, one cycle being idle to full throttle, so to maximise the restored Vulcan's engine life they will not be using full power unless it is absolutely vital and sadly the making of that noise which is what we all remember most, is not vital enough!
