Well, now, thanks to technology, you can actually indulge that fear and check what the chances are of you ending up in a crash with a brand new smartphone app called 'Am I going down?'
While we're inclined to think: 'Well, we'd really rather not know,' the apps developer says it's actually just meant to reassure nervous flyers.
CNN reports that Nic Johns from Vanilla Pixel says it was inspired by his co-founder and wife, Julie, who is chronically afraid of flying.
Using real flight statistics to analyse flight safety, the app basically serves as a way of proving that the chances of you being involved in a plane crash are highly unlikely.
In an interview with Daily Mail, Johns used the example of if you should fly aboard a British Airways flight between London and New York, there is a one in nine million chance of crashing.
He added that more than 10 million routes have been assessed using data from sources such as the Geneva-based Bureau of Aircraft Accidents Archives, the United States National Transportation Safety Board and the Montreal-based International Civil Aviation Organization.
Johns did admit, however, that the launch of the app comes at a bit of an awkward time, following a particular devastating year for air travel in 2014.
