I-TIGI was the aircraft involved in the "Itavia Flight 870" crash into the sea in June 1980. The cause of the crash continues to cause controversy. There is plenty of information in Wikipedia for those who wish to learn more.
"The Nassak Diamond" was originally delivered to KLM in 1965 as PH-DNB and transferred to AWAS who leased it to BMA in 1982. In may 1995 was brought to Taesa who used it until 1999 when they stored it it at Toluca, Mexico.
Whilst the quality is not very good, this is a rare one. It was leased from Douglas between August 1975 and November 1976. It was previously PH-DNE and PJ-DNA and went on to become XA-GOK, N2896W, HK-2865X, FAC-1142 and was broken up at Bogota in August 2004 after many years derelict
