This is going to be hard theres some many aircraft i like but if i have to choose im going to choose 2
The classic plane.
the boeing 707 flown by my grandfather for BOAC and british airways a true pioneer of the avaition industry still going strong today. (sorry about this one guys my grandfather is in hospital i just thought id share it with you)
Modern day.
