English: Replacing an earlier scanned photo with a better version. G-GCAL was the 2nd DC-10 prototype and first flew in Jan-71 as N101AA. This was swapped with the original prototype, N10DC, in Dec-72 when N101AA was delivered to American Airlines. After being stored by McDonnell Douglas in 1973 it was leased to Laker Airways as G-BELO in Jun-77 and operated with them until they ceased operations in Feb-82 when it was repossessed. After a year in storage it was leased to American Trans Air in Feb-83 as N183AT. It was returned to the lessor in Dec-85 and leased to Cal Air International in Feb-86 as G-GCAL. Cal Air was renamed Novair International in Dec-88 and ceased trading in Mar-90. It was stored initially at Prestwick (PIK), Scotland, before being transferred to Waco, TX, USA. In Nov-91 it was sold to Project Orbis as N220AU. After an almost 4 year conversion programme it returned to operation as a flying eye hospital. It was retired in Dec-13 after 42 years in service, not because it had come to the end of it's life but because of a shortage of volunteer DC-10 rated pilots after FedEx converted their DC-10F's to MD-11 standard for two crew operation. The aircraft is currently stored at Victorville, CA, USA.
