Spectrum Technologies Ltd is marking the 30th anniversary of the company’s management buyout (MBO) from British Aerospace PLC (now BAE Systems) on 9 March. Today the international aerospace industry relies totally on the laser marking technology pioneered by Spectrum for processing and identifying aircraft electrical wiring; with around 12,000 commercial aircraft from the global airline fleet in the air at any time, that’s over 1 million miles of laser marked wire circling the planet.
