ST. LOUIS (KTVI) - Over the past year there have been several deadly commercial airline crashes. Dan Gray talked with an aviation expert about whether there may be a common denominator in the accidents.
Tuesday's crash in the French Alps was the fourth commercial airliner crash in just over a year to result in more than 100 fatalities.
In March of 2014 Malaysia Airlines flight disappeared from radar and still has not been found, 239 were on board. In July an Air Algerie flight went down in the Mali desert killing 116. In December an Indonesia Air Asia flight crashed on the way to Singapore, 162 persons died
St. Louis University Professor Emeritus of Aviation Mel Burkart says he believes investigators will be taking a close look at training practices of the airlines involved.
Professor Burkart says early reports of the crash in France say there was a wide debris field of plane parts, and he says that may indicate the plane came apart in flight.
