CA - 5 killed in mid-air collision in San Diego County, 16 Aug 2015

[KEVINinTO]

A small Cessna collided with a Sabreliner private jet operated by Defense contractor BAE Systems. Both aircraft were on approach to Brown Field municipal airport in San Diego.

Here is a picture of what the Sabreliner Jet looks like (not sure if this is the actual jet but this one is operated by BAE Systems - you can see a missile under the fuselage - an unusual feature for a private jet)

EDIT:

BAE operate two Sabreliners. Here is a picture of the second jet (note also missile under fuselage)

BAE were probably testing. They do that at the airport I work at too. It sounds the the Cessna may have mis-heard the tower?
