Authorities are still trying to figure out what caused two planes to crash over Russia Tuesday night, within minutes of each other. Nearly 90 people are dead as a result of those crashes. Officials say the two planes left the same airport minutes apart going in different directions..then disappeared from radar screens at almost the same time...and ultimately went down simultaneously. News 18 spoke with Dothan Regional Airport Administrator Art Morris, who told us.."right now officials can only speculate as to what happened." They do know the planes didn`t have the advantages of modern technology since the planes that crashed, a T.U. 154 and a T. U. 134 were both designed nearly forty years ago. Morris pointed out that just because the Russian aircraft may not have met western standards, doesn`t mean the jet liners were unsafe to fly. Some actually believe terorism could be a possibility because of the timing of the crashes. That, however, is yet to be confirmed.
