Despite apparently reaching incredible speeds of up to 18,000 mph they have never given off a sonic boom.

The cartoons were called Adventures of Sonic the Hedgehog (1993), Sonic the Hedgehog (AKA: Sonic SatAM) (1993), Sonic Underground (1999), Sonic X (2003), and Sonic Boom (2014).

Unlike traditional HE-based ordinance, the pyrotechnic charge produces a subsonic deflagration, not a supersonic detonation, minimizing the blast effects.

Unlike the high explosives (HE) used in traditional ordnance, the pyrotechnic charge produces a subsonic deflagration, not a supersonic detonation, minimizing the blast effects.

The net effect is to shatter (by shock resonance) surrounding material or with object in contact with a resulting supersonic detonation wave.

I have to say that the last two albums we did, 'Sonic Boom' and 'Monster', are great albums, and it will take some time before those become classics.
