Looks like you are taking your job serious Savoia
I'm always amazed how lightheaded grown-up business men are when it comes to buying a helicopter.
The last guy (private pilot) who bought an aircraft from us showed up with what seemed to be his former flight instructor.
By telling me about his flying skills and all of his entries in his licence he reaaaaalllyyyy impressed me
He asked for the registration, radio licence etc. but didn't care about any of the maintenance papers. If we didn't present them to him they would probably still be sitting in the cabinet.
He then asked for a test flight and for a very thorough pre-flight inspection ... and forgot to check for the oil level.
