N720H
Honeywell has been testing their new HTF series 10,000 lb thrust class engine.
N720H Note the test engine on the RH forward fuselage.
And the new replacement aircraft soon to enter Honeywell service N757HW
Here I thought they were keeping an eye on the border.
Subject line should be changed to say it’s a 720, not a 707.
