Does anyone know what height would be normal for aircraft returning to base after an operation? I have the full route from the op order but there is no mention of height. The aircraft Iím interested in crashed into a hill at 1,000 feet on the middle leg of its U.K. route (Lyme Bay - Taunton - Northampton - Breighton).

Iíve looked at the Op Order, the ORBs (both Squadron and Station) the Board of Inquiry Report, the accident report, the Night Raid report, but none of them show any detail.

Thanks
Daz
