I have just got back into GA after many years away from light aircraft. If I find another like-minded PPL who wishes to share the costs of some flying then there should not be a problem. I am astounded however at the lack of experience indicated on these web-sites by pilots who offer sight-seeing and similar air experience flights on what is clearly an attempt to gain financial reward on the pretext of expenses. I well remember, decades ago, being asked by my then flying club to fly a couple of engineers to Biggin so they could fix an aircraft; I knew diddly squat in those days and got hopelessly lost somewhere over East London and it was my knowledge of Geography rather than navigation which got me out of a potential hole. Can of worms methinks............
