Len Cutler apparently knew that. On the 5071A project, we had long meetings about which capacitor to use in the power supply filter. Len wanted to use a mil spec tantalum for reliability, but the cost was astonomical for the large capacitance we needed. We talked him into using a really good aluminum one.
