I think I can shed a little light on this.... For the purpose of flight 
hardware, a crimped connection is better because it is a mechanical connection. 
 If the current through the connector was enough to cause heating in a flight 
environment  ie. vibration, shaking, landing stress, G forces ect,  a purely 
solder connection may pull loss due to melted solder. This situation could make 
for a bad day for a flight crew and passangers......
