Bomb suspected to be work of same man that made Detroit device
It is not yet clear who built the bomb but it appears to be a more sophisticated version of an underwear bomb that failed to detonate fully aboard a plane bound for Detroit on Christmas Day 2009
Authorities suspect it could be the work of master bomb maker Ibrahim Hassan al-Asiri.
Al-Asiri constructed the first underwear bomb and two others that al Qaida built into printer cartridges and shipped to the US on cargo planes in 2010.
Both of those bombs used a powerful industrial explosive and were nearly successful.
